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.

"300 HAM’R
16.25” Barrel
Sierra 110gr HP 2600FPS MV, 1651FP ME
Sierra 125gr SBT 2520FPS MV, 1763FP ME
Sierra 135gr HP Varminter 2400FPS MV, 1727FP ME
Hornady 150gr SST 2240FPS MV, 1671FP ME

300 BLACKOUT
16.25” Barrel
Hornady Black 110gr V-MAX 2395FPS MV, 1401FP ME
Hornady 125gr HP American Gunner 2175FPS MV, 1313FP ME
Hornady 135gr FTX 2055FPS MV, 1266FP ME
Federal 150gr Fusion 1900FPS MV, 1202FP ME

AS YOU CAN SEE THE 300 HAM’R HAS A SOLID 300FPS VELOCITY AND A 400FP ENERGY ADVANTAGE OVER FACTORY 300 BLACKOUT AT THE MUZZLE."

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"

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.

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.
