I was showing my Uncle my 6.8 build and he was telling me about a 300 Ham'r. I looked it up and from the Wilson's Combat website the ballistics look really good especially when compared to the 300 Blackout. Thought I would share.

I wouldn't trade your 6.8 for one.

Oh no.. definitely not!! I just had never heard of it before and thought it was interesting.

Just ordered a WC Protector Carbine in 300 Ham'r. Have several 300Bo, a Grendel and a 6.8. Thought I'd see how it fares. Gonna use the 125gr Pro Hunters on some pigs soon.

Isn't his Ham'R Ar a Hybrid? Not 15 and Not 10, kinda like the DPMS GII?

Not the 300, his 458 HAM'R is a hybrid though.

Tks for the business, trust me your like the 300 HAM'R for hogs and deer. You might consider the 130gr Speer HotCore load for hogs, I've killed over 500 with that load and it really gets the job done. I think you will find that it puts them on the ground noticeably quicker than the Blackout, Grendel or 6.8, the Sierra expands a little to quick for a shoulder shot on a big hog. I'd stick to spine and brain shots with the Sierra.

I just got mine put together. Going out Friday night to see how the 150 gr. SST does on the hogs.

How exactly can you tell this round "puts them on the ground noticeably quicker than the Blackout, Grendel or 6.8"? When I shoot a hog in the head with my 300BLK its a bang flop.

Also have you compared the 300 HAM'R vs the 300BLK in short barrels down to 8 inches? Does the Ham'r still retain the velocity and energy gains over the Blackout or does it need the longer barrel lengths to achieve the gains over the Blackout?

The 150SST does great on hogs, just doesn't shoot quite as flat as the 130s. I used the 150SST on all the big stuff like Elk, Waterbuck, Addax and Oryx I've show with good results.

As any experienced hog hunter knows a 5.56 is all that you need for brain or spine shots, but we don't always have the opportunity to take those "ideal" shots and have to go for a lung shot from time to time. Also as we know big hogs very rarely go down quickly with a lung shot and almost always run 20 to even up to 100yds. I've shot a lot of hogs in the lungs with a 6.8, .308 and 300 HAM'R and based on "my experiences" they normally run further when shot with a 6.8 than they do with either the .308 or 300 HAM'R which seems to put them down the same. The only calibers that I've shot hogs in the lungs with that put them down really quick is the .458 SOCOM/HAM'R or a 9.3x62 with 286gr Nosler Partitions.

We have only built pistols with 11.3" bbls and mine gives 2320fps with the 130gr HotCore and still shoots sub-inch, it's my "car gun" for traveling.

We did a velocity test with the same bbl gradually cutting it from 20" down to 12.5"

ALL TESTING WAS DONE WITH THE SAME BARREL PROGRESSIVELY SHORTENED FOR NO BARREL TO BARREL VARIATION AND ALL AMMO FOR EACH LOAD FROM THE SAME LOT. ALSO ALL SHOOTING WAS DONE DURING A 5 HOUR PERIOD ON THE SAME DAY USING A LABRADAR TO MINIMIZE THE EFFECT OF ATMOSPHERIC CONDITIONS. ALL CHRONOGRAPH STRINGS WERE 10 SHOTS WITH THE HIGH AND LOW SHOT REMOVED FOR AN AVERAGE OF THE REMAINING 8 SHOTS.

AS YOU CAN SEE AS THE BULLET WEIGHT WENT UP BARREL LENGTH HAD LESS EFFECT ON VELOCITY. AVERAGING THE 16.25” TO 20” NUMBERS IT WORKS OUT TO 10.5 FPS PER INCH.

Great Question!!

I ran some numbers using the Wilson 300 Ham'r 125gr Speer TNT and the Hornady 123gr SST. I used Wilson's website to get there info and for the Hornady I used numbers that I chrono'd from my 12.5" 6.8 barrel and then plugged that into Ballistic AE. Remember the 6.8 is from a 12.5" barrel and used a 50 yard zero

At 50 yards the Ham'r had around 7.7% more energy. Equal zero
At 100 yards the Ham'r had around 6.5% more energy. 6.8 was +0.8" and Ham'r was -0.1"
At 150 yards the Ham'r had around 4.5% more energy. 6.8 was -0.1" and Ham'r was -1.9"
At 200 yards the Ham'r had around 3% more energy. 6.8 was -3.0" and the Ham'r was - 5.7"

So the Ham'r with custom ammo is barely out performing a 12.5" 6.8. I'd be willing to bet that with hand loaded 120gr SST they would be at least even if the 6.8 wasn't ahead. Not saying it's a bad round but for it to be said that it kills stuff deader is marketing hype.

Appreciate the information, but I like my barrels really short so I'll stay with the BLK. Also I don't know if I'm reading that correctly, but are you saying the 300 HAM'R is on par with the 308WIN? That is impossible due to just the sheer volume of the 308 case compared to the 300 case and both shooting the same projectile.

I’d be more impressed with your opinion if you owned one and did a hog killing comparison of the 2 calibers. I will be doing my own comparison with my WC 6.8. And you are right many in the gun industry could learn about effective marketing from WC. I’m living proof I own 3 different calibers now and am a very satisfied customer. Other friends on this forum have used my rifles and commented on the difference in quality from their rifles.

Not here to impress you Sir. Just call it like I see it

Let’s take hog killing out of the discussion and talk about the HAMR being able to step up to the 150 gr. 30 caliber space and kill elk, oryx effectively would you try that with the 6.8 120 gr. SST?

I don't hunt Elk so I can not give you any input on that. That being said I have read many posts of guys taking elk without any issues with a 6.8SPC.

Again I never said it wasn't a good caliber. What I have brought to attention is statements made


And from their website "has proven it to kill much more effectively than the 6.5 Grendel, 6.8 SPC, 7.62×39 or 300 Blackout."

So what? It’s marketing a new product and it seems to be working for them.

All about marketing product with statements that are valid. Who knows time may tell that it is the best caliber but to make those claims with after shooting 200 hogs I call BS.

So who decides what statement is valid?

No matter what either have to do better than the blackout

Maybe you will when you get yours


I want to here from real world hunters that use it for some period of time. You don't run out and buy a new truck based on claims that it will outlast all others after they only tested it for a few thousand miles. Well at least most don't

I would agree with this statement

You do realize your doing the same thing with your advertising tag line on all your posts?

I’m a fan of the 6.8 but I am sure there are many that would call your statement invalid no?

I am sure there are people that would say that and they have that right. I make that statement after 8+ years of hunting with and building the 6.8, not 200+ hogs.

The 6.8 has a much longer track record of being a good hunting caliber than the Ham'r. Over the years I've had many people trade in their 5.56, 300 BO and even 6.5 Grendel for a 6.8SPC, also never had a customer complain about the effectiveness of the 6.8 so there is some merit to the statement.

I did take a Red Stag with 6.5 Grendel 123gr SST. Two shots through the boiler room. One punched all the way through. The other stopped in the opposite shoulder. 75yds

Don't care much for comparing, they all get the job done. Can't wait to try this Ham'r out tho.

Thanks! Will try it out for sure.

First off I'm not trying to start a pissing contest here, just commenting based on my personal experiences and those of the people I trust.

Where's the 200 hogs reference coming from? I've personally shot over 500 hogs with the 300 HAM'R now, 183 of them YTD since Jan1 with several over 200# and one 320#. I know for a fact that we've sold over 25 300 HAM'R rifles in Red River county TX alone and I know of one guy that has already shot over 200 with his so I'm sure the hog kills are over 1000 by now just in Red River county. I also shot 22 deer, 1 Elk, 1 Oryx, I Waterbuck and 1 Addax too. My buddy Terrill from NC shot the first black bear with his. In my mind the caliber is well proven in the hunting field. I'm taking one to South Africa in Aug so we'll see how it does on African game???

Don't get me wrong I still have several 6.8s, like them and have shot a LOT of game with them. But based on my "personal" experiences the 300 HAM'R will put a hog on the ground quicker that the 6.8 with a shoulder/lung shot. When you hunt in NE TX river bottoms like I do the less they run the better, especially in the summer when the snakes are out!!!

Me either, I'll post my results. Yes they do get it done if you can do your part.

Don't consider it a pissing contest Sir, Let me state again that I am not saying that it's not a good caliber. The video linked is where I heard the 200 hogs but I stand corrected. It was stated that it was field tested on over 200 hogs, not just 200. We have all seen marketing of a caliber that it's the greatest and then after people get one and actually put it to work it falls short of those claims. I am not saying that your Ham'r will fall short of what was stated. I'm sure that it has had more use and testing since it was released but from the beginning it was stated in this video that it had nearly the same effectiveness in the field as a .308 and that it kills better than the 5.56, 6.5 Grendel, 6.8SPC and the 300 BO. At the time these statements were made it was stated that it had been tested on over 200 hogs, not 300+ but over 200. I find this a low number to claim it kills better than all the other AR-15 calibers.
Video

Again not saying that it isn't a good caliber and you could be correct in all your statements. I do not have a 300 Ham'r so I have based the velocities off of your website and according to the numbers it is not that much better than a 6.8 inside of 200 yards. The 6.8 overall shoots flatter and past 200 the 6.8 has the slight edge. Time will tell

Video was shot last July if I remember correctly, been a LOT of hog killin done since then. Yes time will tell.

I think you are splitting hairs with the power levels of the 6.8 SPC, 6.5 Grendel or 30 HAM'R. I personally wouldn't use any of them on Elk sized animals.

This is just like any other caliber debate, it's a waste of time to have a sword fight over which one kills hogs better. Wilson Combat is too good to introduce a new option that doesn't outperform existing commercial options on paper. So that's a given.

You just have to make a decision based on your use case. If the marginal gains outweigh the lack of widespread commercial support, then by all means go for it! I'm sure it will work great. It's just like picking anything else, for the most part you are going to sacrifice a certain amount of performance to get cheaper ammo with more options and availability.

All I can say now due to a NDA is that "widespread commercial support" may not be far away.

Somebody needs to harvest a few 200+ lb boars and do a test at 100 yards and test different calibers to see how much penetration each get through the shield and shoulder. There are just too many variables in live hunting to say whether one has more knockdown power than the other especially when different people aim for different spots. Obviously head/neck shots are going to drop them more than shoulder/behind the shoulder shots.

either way the ballistics compared to 300 blk and 7.62 are impressive in an ar-15.

Im just curious if the man behind the screen name is Bill Wilson. I know he shoots a ton of hogs.

Yes it is. He posted and introduced himself in mikei’s 300 HMR thread a few weeks ago.

Cool.

Don't blink, or you'll miss its passing too... much like their poly-framed 1911s (KZ45), there's just not enough market interest to keep it around for long.

We've shot quite a few 200#+ boars and two over 300# (actual weighed on a scale) and have done a lot of bullet recovery testing on dead hogs. You can see some of this in our videos on the web site. Both the 130gr Speer HotCore and the Hornady 150gr SST have more penetration than is needed for any shot angle and blow through the toughest shield. Weight retention is usually in the 70% range which I consider ideal since the other 30% is fragments that often do a lot of damage. BTY you never want to shoot a hog behind the shoulder, there are no vitals there like a deer. The "ideal" shot is with the hog quartering to you and shoot them in the center of the neck, plan A will be a severed spine and a DRT hog with the bullet penetrating to plan B which is the lungs which usually ends up with the hog running 20-100yds.

No comparison here and the reason we discontinued the KZ series is that we could never learn how to make them at a profit if sold at a competitive price. They were good guns, especially the 9mm version and we still have plenty of magazines and spare parts to support them. Our EDC X9 series is a better gun and we can build them at a profit.

More choices are rarely a bad thing.

I wish you the best of luck with your .30 cartridge.

So pops took my Protector 300 Ham'r to the range while I'm stuck coaching baseball all week. He loved it. Topped it off with an Athlon Midas BTR 1-6 and got this 3-shot group at 100yds w/125gr Pro Hunters. Can't wait to try it out on some piggies.

Nice group. I'm headed out tonight with mine shooting the Speer 130 gr. Hot Core.

Keep us posted

The round performed as advertised. Shot 3 hogs, boar weighed about 225. Nothing ran more than 20 yards. Rig ran flawlessly as I expect from WC.

That guy that assembled everything did a good job

Cool . I got a guy at work building one as I type after I sent him the info about this round and he saw the barrels were on sale recently

I made my 200th hog kills since Jan 1, 2019 with the 300 HAM'R last night bringing my YTD total to 203 (2 were with the new .350 Legend and 1 with my .358 Win) and well over 600 hog kills with the 300 HAM'R over the past 15 months. Of all of the hog hunting I've done with the 300 HAM'R I've had no more than 12 hogs that I didn't recover and these were all due to either my poor shot placement and/or bad judgement. Most of the kills have been with the Speer 130gr HotCore, but several have been with the 110gr Hornady or Speer SP or the 150gr Hornady SST (.300 Savage variant). This is just the hogs that I've personally killed and doesn't count the ones other hunters have killed that I guided here at the ranch.

I consider the caliber well vetted as far as hunting goes.

you must really hate those hogs and have a lot of time to dedicate to killing them

funny you mentioned 350 Legend, I 've thought about trying that cal as well

My ranch and the one of my good friend/neighbor is in an intensive management program with the TPWD with 10,500ac under management for deer and the biologist assigned to the property has instructed us to shoot 70% of the hog population annually to maintain a consistent hog population on the ranch. We shot over 400 last year and 200 YTD this year and I still see as many hogs as I did two years ago. The ranches are ideal hog habitat so they just thrive here. I hog hunt on average 5 days a week for 4-5 hours. I also have access to several thousand acres within a 45 min drive up on the Red River too.

So far the Legend hasn't impressed me, but I'm limited to the Win 145gr FMJ and handloads with prototype Speer HotCore bullets at this time. The cartridge was brought out way before there was adequate ammo/components available. NO suitable bullets are on the market today and only Starline makes good cases. The case heads on the Win cases are too soft and so they aren't reloadable.

Wilson Combat, do you know where Cross Arrow ranch is at. I am on a lease there, do a lot of hog hunting and course deer hunting.

For what it is worth, there is no marketing hype associated with the 300 HAM'R. If anything, I would say Bill and his crew have downplayed what the HAM'R will really do.
Yes, this if my first post and I am known to be a bit opinionated. But I was allowed to follow along with the development of the 300 HAM'R and have been playing with it long before it hit the market. For total exposure, I will say that Bill Wilson and I are good friends and he is the one that told me about the forum. He knew I was sick of another forum that thinks they know everything and posted nothing but negative bs. However, I have no ties to Wilson Combat other than being a customer.

As we all know, friendship only goes so far when you're talking about your personal hunting rifles!

As far as the 300 HAM'R, I drank the Kool-Aid about a year ago during the development. After watching how hogs, deer, and even one black bear reacted to the 130 grain Speer Hot Core bullet out of the HAM'R I become a true fan. When the first two shots I took with the final version of the 300 HAM'R accounted for four hogs (two doubles and they were all in the 150 lb. range) I told Wilson he would have to listen to me tell this for years to come.
There is no way I'm going to say that the 300 HAM'R is better than "X" or "Y" because we all have our favorites, but I will say it is the best mid-range cartridge I've taken game with. It is almost as if WC built this cartridge for me. I really don't care what any rifle will do past 200-250 yards because I won't take a shot beyond that distance. What I've seen the HAM'R do within that range is outstanding. There is also no way I can relate the feeling of seeing that black bear crumple the nanosecond it was hit. Yes, all of the above could just be pure luck, but I've got an idea there is a whole lot of luck left in that rifle.
Just for a moment, I will actually give a few details of the cartridge other than my personal feelings. The parent case is the .223/5.56 and it is easy to form from surplus brass. (Even though you can buy new brass, I'm cheap!) The pressure is on par with the .223 Rem. and well below that of the 5.56 NATO. The only thing needed to convert an AR-15 is a barrel. It will function with a standard magazine but the magazines designed for the 300 Blackout are perfect. Being a .30 caliber, there are an awful lot of bullets that can be used in reloading, (I favor the 125 Sierra ProHunter and the 130 Speer Hot Core.)
I wish Bill good fortune with his sales, and I see a bright future for the cartridge. I would imagine other companies will start to notice the 300 HAM'R. (remember, it took the 6.5 C a decade before it was "the thing")

But for me, it really doesn't matter. I have mine!

Taking this at a pure technical slant, I.e. nothing against Mr Wilson , appreciate and respect what he offers the gun community and his affinity for killing hogs

The hype and/or marketing team screwed up with the still published statement “kill much more effectively than 6.5 Grendel , 6.8 SPC II...”

All comparison data I’ve seen to illustrate this has been against 7.62x39 and 300 blackout

Technically the energy and velocity of the 130 gr HotCor could be the deciding factor on the 300 Ham’r statement made but it is less versatile, less mainstream than both 6.5 Grendel and 6.8 SPC.

All the special killing power is in one bullet so far as I read the reports , it can’t drive and erupt other .30 cal bullets as well as its .264 and .277 comparables.

Welcome to the board - and I’m glad Mr. Wilson asked you to come clarify things on this forum.

I hunt all calibers and don’t have skin in the game but it just bothers me to read that this 300 Ham’r kills more effectively than time tested and more well rounded designs.

My 2 cents not needing to be validated

First let me say thank you. It is very refreshing to see someone disagree so politely.
Actually there are 16 different bullets in the 110 to 150 grain range that have been tested and found suitable for the 300 HAM'R. The 130 Speer HC is one of my favorites because of how it performs and the fact it's cheap! All too often we think we have to buy a high-end premium bullet to get good results on game. Lately Bill has been favoring the 150 SST a little more. But this cartridge is not based around any one bullet.

But I may have to agree without argument that Dead is Dead and there is no way to make something "Deader." But, I've tried about every cartridge out there since that is part of my job, and I have been highly impressed by the visible effects of the 300 HAM'R on live game.

I will agree completely that the 6.5G and 6.8 SPC are more mainstream, but I would disagree that their design is more well rounded. At the same time, they have been around for several years while the 300 HAM'R has only been out for months.

I personally think one of you Texas boys with a lot of hunting land needs to invite everyone out for a side by side comparison. It's been about six months since I have had the chance to visit TX and kill a few hogs.

graycard

Agree with this!!

1) What are the 16 different “suitable” bullets? What do they look like when recovered from gel or game animals?

2) Let’s see some of the recovered 150 SST, I can’t imagine they are mushroomed very far down the shank, but I may be in for a surprise...

3) but yet that’s what the 300 ham’r website claims, more effective than XX and XX calibers...

4) we have many magazine options for 6.5 and 6.8 that allow for longer COAL, a few chamber variations, 24” Grendel barrels that take advantage of longer barrel length in the velocity category. On and on.... not too mention a bit more powder capacity in the cases. We got some steel cased CHEAP plinking ammo options as well.

4a) ballistics are a funny thing - I’ve witnesses 6.5 Grendel 90 grain TNT bullets penetrate through hogs and get double kills, also take down a handful of 280+ lb’ers. So I attempted to copy that formula (fast varmint bullet) with the available 308 Nosler Varmageddon - didn’t even come close in performance in the penetration dept.

But both pills weighed 90 grains and on paper then 308 had more velocity and energy.....

These are the areas I look forward to seeing more data on for the 300 ham’r respective to above highlighted 16 bullets

5) easier said than done - I just got off my lease so I’m of no use in hosting a hunt or shoot off.

In the meantime i guess the show and tell will have to be internet based.

I’m not a 6.5 Grendel fanboy, I just have a lot of experience with it to relate , if anything i prefer 308 win or a good mid bore wildcat....

Hopefully this thread evolves into an archive of good data on the 300 Ham’r that is visited from far and wide to see how it performs.

I was wrong, it is 17.

I left the ballistic gel to Mr. Wilson and I think there are some videos on his website showing the test. As for recovered bullets, everything I have shot has been through and through. I do know he has set up a few hogs (pre-killed to make them more willing) and recovered some of the projectiles. Hopefully when he gets back in town he will post a few photos.
The load data on the website covers the 10 loaded cartridges they are selling at this time.

One little item that I have not seen brought out in the posted loading data is that the velocity listings are an effort to hit certain pressure nodes. During load development it was found that each bullet had a certain pressure level that gave the best accuracy. Since a handloader, such as myself, doesn't have a pressure barrel sitting around we have to use the velocity readings to try and come close to the proper pressure level. The loads listed are based on the velocity and pressure that gave the best accuracy for each bullet.
I have shot some of these bullets at much higher velocity than you will ever see posted, but a company like Wilson Combat can not control everyone out there trying to wring out a few more fps. Since there are no restrictions on who may make a barrel, or build a complete rifle, WC has to put safety above all else.
For my own loads, I found out that gaining an extra 100 fps may have given me a little bit of bragging rights but also resulted in a drop in accuracy. Since above all else, I am an accuracy nut, I chose to back off to the best accuracy level. The game I have shot didn't know if they were hit with a 2550 fps projectile or one traveling at 2700 fps.

Mr. Popper, I like your attitude. Since my playing with the 6.5G and 6.8 SPC was restricted to certain factory loads, I would love to hear about their performance and capabilities from some who have developed good (and safe) field-tested loads.

I will freely admit that I would react as you if I saw a release of another AR cartridge. My first thought would be why? That would soon be followed by; "You've got to be kidding me!"

But lets give it a little time.

I’m outta my league, Im just hunt with my wife and kids guy

150 and in, we’ll pull the trigger

Y’all may be onto something, I’m liking the idea

But we’ve spoke on here several times prior, a lot the “new” is marketing

If WC can get the ball rolling, it could turn into something

I’ve had several AR’s, my daughter is killing it w a 556

I’m not the type and I suspect many others are with me to not buy something we have to hunt for ammo

It’s taken me this long and I was really on to the 300 BO, but have yet to buy it

Time will tell

What’s the same ballistics on a 8” 300BLK I’ll supply the rifle if you want to test it.

Sorry sir, I really don't know what you are asking.

KRoyal is asking for the ballistic comparison data between an 8” 300 BlkOut and the 8” 300 Ham’r.

If there is no data available, he is offering to send his 300 blk out barrel to y’all for chrono use.

Here I need a translator and I thought you guys were Southern!

I appreciate the offer (it does sound like fun) but right now I don't think an 8" HAM'R barrel even exist. So anything I do wouldn't be an "apples to apples" comparison and that is the problem we see in a lot of "this beats that" internet comparisons. My rifles are 16", 18", and I'm just waiting on a buttstock and optics to get a 20" going.

Of course, since this is the internet, I could claim to be an expert on SBR's and AR pistols, but I think you guys would spot the BS a mile away!

Besides, if I shoot something with a barrel that short it is gong to be a "N" frame S&W with a DEEP blued finish.

Thank you

KRoyals request was a good one : here is the link for the 8” Ham’r barrel

Maybe when Bill gets back in town he can share the comparison data...

Sounds like the HAMR has skills and magic that make it better then all the other AR15 gap calibers.

Never seen a guy so hung up on a caliber he'll probably never use. Move on
Thank you Mr Wilson for giving us another choice

Ah Pappy , you’re missing the point - This is a discussion about ballistics, of which I’ve used many calibers based off the parent case of the Ham’r.

I’m moving in , not on ...

Is it possible to fire a 300 bo in a 300 hamr? It's not a good idea but could it happen?

Good question.
With the vast difference in the dimension from the case head to the shoulder between the 300 HAM'R and the 300 BO I don't think the BO would fire in a HAM'R. Nor would the HAM'R seat in a BO chamber. However, in my mind I can imagine a BO with the bullet seated too far out actually "head-spacing" off of the rifling and thus being capable of firing. But then, I can't imagine a BO with the bullet that long being able to fit into the magazine.
I'll let someone else experiment with this one.

Pat's Cross Arrow ranch is across the Cuthand Creek from us and we border his Hart's Bluff ranch of which I lease a little over 1000ac of

I just tried chambering various 300BLK ammo in the 300HAM'R and all of them chambered ahead of the extractor (including Rem 220gr OTM) and had to be knocked out with a cleaning rod. Based on this I don't think you could get a BLK to fire in the HAM'R.

I don't have a 8" BLK here at the ranch and we don't make 8" 300 HAM'R barrels, but here's a comparison of my two 11.3" pistols

300BLK
110gr Hornady V-MAX 2251FPS-A
125gr HSM Sierra SPT PH 1966FPS-A

300 HAM'R
110gr WC Sierra HP 2431FPS-A
125gr WC Sierra SBT PH 2393FPS-A

As a FYI we just started experimenting with a new powder for the 110gr loads and it looks like we can gain close to 100fps with it, we just run out of powder space with the light bullet loads using CFEBLK before we get over 50k PSI

I just got an email from one of our customers with a couple of nice photos of a 300# and 375# black bears taken in ID with his 300 HAM'R, he said one dropped DRT and one just took a few steps.

First, comparing a 300 blackout and 300 HAM'R, well... Can decide for yourself



I've been using the 300 HAM'R since before it was introduced, shot dozens of hogs. What I really think is why it is superior to the 68 is reloading, ammo, etc. Conversion of 556 brass is simple, and brass is cheap compared to the 68.

As for loads, my current hog load is a 110gr Hornady Spire Point, out of my 16" WC rifle I'm at 2738 fps. When deciding what is effective, comes down to killing. Almost all of us on Team Oink have switched. Even if you buy new brass it's only $30/100.

It kills, DJ dropping a few :



It's not a replacement for anything, it never has been advertised as that, it's an option, it's an easy conversion of existing rifles in many cases. It's a blast to shoot, low recoil, and very effective. I won't get in to comparisons, my feeling is, run what you brung and have fun doing it.

As for team Oink, we're sporting the 300 HAM'R. Carry on.

Thanks for the info Bill. Wouldn’t mind trying a 300 Ham’r out, but I’m heavily invested in the 300BLK with reloading supplies and very spoiled with the 8” barrel, even with my 8” suppressor attached it’s a bit shorter than a unsuppressed 16” carbine.

Sorry if I missed it somewhere but what’s the case length on the 300 hamr

dk... this is a ruff crowd. you can't just post a vid of one hunt and assume everyone's dream just came true. here's that hunt bundled in with a few other shots...

hd i really don't know why you bash the hamr on every forum where it's discussed. if you'll remember, i tried to hunt with one of YOUR 6.8 builds, but you couldn't get the jamming pos to feed reliably. all you do is assemble parts. you don't build anything!

talk about marketing hype? where was your guarantee when my gun wouldn't work? when i posted my disatisfaction with your product on the other forum, i believe you insulted me and called me a derogatory name. is that what all your customers who have a complaint can expect?

u need to hear from real world hunters? here... i'll just leave this here for you to ponder. and by all means... please post up all your kill pics and vids from your whopping 8 years of hunting.

i certainly don't hit everything i shoot at, nor do i kill everything i hit. but i've shot more than a few pigs with every bullet wilson combat lists loads for except for the 150s. i've got no complaints... nor shortage of dozens more vids.

Wilson Combat is a name id trust, I don’t own one but like to one day

Good to see you Djones

Bill just FYI, I was looking at the 300 HAM’R barrels on your site and where it is comparing it to 300BLK “more” is misspelled twice and where it’s talking about the reloading dies “available” is misspelled. Sorry the website designer in me notices stuff like that lol. Just a heads up.

Good job on the free advertisement Kyle. Stop trying to get a free rifle

Haha yea I wish, just my OCD.

1.603" min

Tks, I'm on it

I have to say after reading all this, I'm getting interested in the 300 hamr. Debating on this or a 350 legend when I get a chance.

Djones is a legend and unlike Kyle I am not invested in 300brickthrower.

Has there been a mention of optimal barrel length?

I like throwing bricks, faster than my 68 could

DJ and CF are using 18's, I'm using a 16". I'll be using the 11.3" here shortly, working on some loads.

I'm using both 14.7" and 16" for uppers with a can and 18" if I'm not running a can. Here's a test we did, as you can see the 150gr load didn't loose much as the bbl got shorter. NOTE: none of the loads used in this test are at MAX velocity.

BARREL LENGTH EFFECT ON VELOCITY
300 HAM’R

125 SIERRA SBT PH 20" bbl 2534 FPS
125 SIERRA SBT PH 18" bbl 2498 FPS (-36)
125 SIERRA SBT PH 16.25" bbl 2486 FPS (-12)
125 SIERRA SBT PH 14.5" bbl 2441 FPS (-45)
125 SIERRA SBT PH 12.5" bbl 2367 FPS (-74)
TOTAL VELOCITY LOSS FROM 20” TO 12.5” 167 FPS

130 SPEER FNHC 20" bbl 2485 FPS
130 SPEER FNHC 18" bbl 2460 FPS (-25)
130 SPEER FNHC 16.25" bbl 2438 FPS (-22)
130 SPEER FNHC 14.5" bbl 2412 FPS (-26)
130 SPEER FNHC 12.5" bbl 2346 FPS (-66)
TOTAL VELOCITY LOSS FROM 20” TO 12.5” 139 FPS

150 SPEER FNHC 20" bbl 2202 FPS
150 SPEER FNHC 18" bbl 2194 FPS (-8)
150 SPEER FNHC 16.25" bbl 2171 FPS (-23)

150 SPEER FNHC 12.5" bbl 2105 FPS (-41)
TOTAL VELOCITY LOSS FROM 20” TO 12.5” 97 FPS

ALL TESTING WAS DONE WITH THE SAME BARREL PROGRESSIVELY SHORTENED FOR NO BARREL TO BARREL VARIATION AND ALL AMMO FOR EACH LOAD FROM THE SAME LOT. ALSO ALL SHOOTING WAS DONE DURING A 5 HOUR PERIOD ON THE SAME DAY USING A LABRADAR TO MINIMIZE THE EFFECT OF ATMOSPHERIC CONDITIONS. ALL CHRONOGRAPH STRINGS WERE 10 SHOTS WITH THE HIGH AND LOW SHOT REMOVED FOR AN AVERAGE OF THE REMAINING 8 SHOTS.

AS YOU CAN SEE AS THE BULLET WEIGHT WENT UP BARREL LENGTH HAD LESS EFFECT ON VELOCITY. AVERAGING THE 16.25” TO 20” NUMBERS IT WORKS OUT TO 10.5 FPS PER INCH.

I WISH WE HAD STARTED WITH A 22’ BARREL BECAUSE IT LOOKS WE STILL HAD POWDER BURN PAST 20” WHICH SURPRISED ME.

I keep a 16" version as my everyday rifle, but use an 18" model for my hunting. However, it is the difference in the scopes I have mounted more so that the barrel length.

Sic em djones

You really can't use djones videos as proof the 300 HAM'r is a better round. Pretty sure he could kill a pile of hogs with a slingshot and bag of marbles if he wanted to.

Seriously though, looks like a good round.

Nah you haven't hunted with him lol

Knew it was just a matter of time before you would start flapping your gums. First of all not bashing the Ham'r and don't believe I ever said it was a bad caliber. What I have questioned are the statements made that it is a better killer than 6.8 and 6.5 Grendel after only a couple months and a little over 200 hogs killed with it.

Hundreds of uppers built or as you call it, assembled and I've had 1 that would not group well. I got it back and fixed it. No other issues. As far as your upper goes. You stated it jammed consistently every 5-8 rounds. I asked you to send it to me. I ran 60+ rounds through it on 2 separate lowers with multiple different mags and it run just fine without a single malfunction. I told you it had to be a mag or lower problem. You said it was not because your friend assembled the lower and it was right. I told you it wasn't the upper but since I didn't have my FFL i could not receive it to check. I then told you that maybe we could meet up sometime. You said don't worry about it for now that you were going to get an LWRC because that's what you really wanted. I don't recall what I called you but I can assure you it was probably because there was nothing wrong with the upper when tested by me, I offered to try and meet up, never heard from you again until you brought it up on another forum.

8 years hunting??? Where you get that? Just more flapping of the gums. I started hunting with night vision and thermal 8+ years ago but been hunting my entire life. I don't video

omg you're back. i love this! there are only a few, and i mean VERY few folks i will call out, but you are a special project. i'll participate until the thread gets locked down. let's see... how about we begin here...



here's where i got it. see if it rings a bell. it's nearly as long ago as the conversation we had you seem to recall so well



first of all, it's the miles, not the years. i probably killed more hogs in the last few months than you have in however many years you want to pretend you've been hunting.

regarding the 6.8 rifle... i don't recall you offering to meet, but i'm too far away to meet you even halfway for a 'guaranteed' rifle. i said this, you said that... ad nauseam. you said send it back and you'd get a new upper trued up and swap with me, then you'd send the suspect upper to aero for them to test for tolerance. you never did. do you deny that? if so then you are a liar. i sent you multiple vids of the gun jamming in the field and also cycled manually, by both the charging handle and with the bolt release. true? and you couldn't duplicate it!!!??? no one in business should EVER equate 'not being able to duplicate the problem' with 'there is no problem'. i said forget it only after you sent it back without doing what you promised. i was tired of wasting my time with someone who would not honor their warranty, so i got an LWRC at that time.

all you were doing in this thread was whining because a new caliber/product might jeopardize your side business by taking a few sales away. your remedy... bash the competition. all you're doing now is trying to mitigate any perceived damage caused by a customer complaint. guess what... you're the one doing all the damage! the smart thing to do would be to buy some 300 hamr barrels and assemble a wider range of products. whatever you do, don't quit your day job!

geezzz, i feel like doc holiday when he challenged ike clanton to a spelling bee. to everyone else, sorry for the rant, even though i bet a lot of you find it entertaining, lol. anyway, hope this will make up for it...

I pray this thread don’t get locked

I'll back DJ on this, the problem was the upper, not his lower. We tried in many scenarios with many lowers, including mine and CF's. The problem was the upper receiver itself so there is no way you could have tested appropriately.

LMAO!! I don’t care that you back your buddy. I know what I did when it was sent back and it ran just fine. I find it funny that this has never been talked about since DJ and I’s last conversation close to 2 years ago until this whole Hamr issue in which you are Wilson Combat pro staff and you and DJ are best buds. So of coarse you’ll defend WC and side with DJ.

Oh you can say anything you what you want on here with the hopes someone believes you, I don't really care because people will make their own judgements one way or another. We changed the upper receiver and it worked fine. Your personal attacks on me and others are consistent with previous posts. Let's really look at what you do, you attack anything that is in competition with you or products/parts you sell. On 68 forums it was WC the 300 HAM'R, but there's a little more to the reasoning of these attacks now isn't there? Most businesses stay out of the politics, attacks on others businesses, agree or disagree. However, that's not the case with you and a few others. Ilike another thread on arfcom of another business saying the 300 HAM'R can't shot 150gr bullets.

OH dang, I am WC Pro-Staff, how'd you know that? Oh wait, it's been in my signature the last two years and everyone already knows.

Never went anywhere
Read it again!!

That's 8+ years hunting with the 6.8, not how long i've been hunting.


I find this statement comical.

I did offer to meet you sorry you don't recall. You did send a video of the rifle malfunctioning and I also sent you a video of the upper running with out any issues. I onlyThe first thing I did when I got it was test fire it and it did not have 1 cycling issue. You stated it was every 5-8 rounds. I put 60 rounds through it and not one hiccup so yes I sent it back and said there was no problem. If there would have been an issue with a receiver out of tolerance then yes I would have installed a new one and sent the old one to Aero BUT there was no cycling issue when I shot it. That is why I said it was mags or lower. You can't fix a problem that doesn't exist. I never said there was not a problem with your rifle. I said it wasn't the upper which leaves ammo, mags and lower.

Back to the Ham'r part. I believe I have never said it was a bad caliber. All I've said is I don't believe the claim to be the best or most effective killing caliber in an ar after only 200+ pigs are killed with it. There are others that have posted the same thing

i know what you did too... nothing! please correct me if i'm wrong. you say you couldn't duplicate the problem, but i clearly demonstrated it in vids many times. wth did you think would happen when you sent it back untouched. fyi... cf bought it from me and put a new upper on it. works fine now. that's all it took. and you could have avoided all this by doing the same thing yourself... LIKE YOU SAID YOU'D DO!!! any chance tolerance stacking between marginal parts may have been involved after parts broke in?

i haven't said anything about it because it wouldn't do any good. waste of time. i only bring it up when i see you bash wilson combat because you don't have any room to criticize ANYONE in the firearm business. yes kamps is my friend and he's affiliated with wilson combat. if there is anyone here who wouldn't stand up for a friend, sound off so i can include you in this... crickets... yep hd... you're alone in that regard.
