I haven't had any function issues with a low mass BCG as long as the rifle is gassed properly and it's kept pretty clean and lightly lubed. The only issues I've had is with a dirty/dry gun in cold weather. That said, if I had to go to battle I'd want a full weight BCG in my rifle.

We're having excellent testing result with BCGs coated with DLC by Armorlube. As recommended by Armorlube we're running these completely dry. Apparently this is a new Mil-Spec and Colt is switching to it for govt contract M4s. I've been running one of these in my primary "suppressed" hog hunting rifle for months now and the only maintenance I've done is clean the chamber and wipe the BCG down with a paper towel. I've had 0 malfunctions.

Thanks for the reply. I typically do full mass bcgs for the reliability factor but this gun will be more of a sports car…looking forward to seeing what the hamr can do, I’ve built multiple rifles with WC barrels and have nothing but great results with them.

So I have a M17S in 7.62x40 WT which cycles quite well with a can but ALMOST cycles without one (about 30% of the time). I realized that buying .300 HAM'R brass from Starline actually costs less than the reloading components I was using to fireform each 7.62x40 shell, to say nothing of the time investment. So there really isn't a justification for staying with the older version beyond sunk cost, which is surprisingly cheap to recoup. My big question is this: can an extant 7.62x40 WT chamber be reamed to a .300 HAM'R? My assumption was yes given the similarities, but since Bill is kind enough to make himself available I figured that I'd ask directly.

I also wanted to thank him for the pics of expanded 150 grain Interlock SPs....I had planned to use SSTs, but that the SPs seem markedly better AND being a shorter bullet allow a bit more powder. I have mentioned this on most of my posts, but thanks again for a great round.

Yes, we have re-chambered several 7.62x40s to HAM'R

I just found some Winchester #41 primers on sale ($25 a brick cheaper than the CCI 450 I normally use) and was wondering if anyone had any experience with these. Since I'm pretty sure they're the same as the ones used in the Lake City 5.56 ammo they should be OK but thought I'd ask.

I have used a lot of both. Got into the 450's when the 41's ran low. No doubt there are differences in some cases (6.5 Grendel) but I noticed no differences in any 300 Ham'r loads.

No issues using 41s

Well done, good hog. Nice double tap

300 HAM'R - priceless
DJ shooting - priceless
Music - lol

Received my rife yesterday and it is real fine piece of gear. Working on loads today and hope to get to the range this weekend. Thank you to Bill and his team for such a fine rifle and an blazing time from order to delivery.

Sure like my HAM’R Ranch.

I’ve got a H&R Handi rifle in .223 what would be the possibility of getting it rechambered for 300 Hamr? Is this something a local gunsmith could do..? I’ve never done this before so just looking for some info/advice. I’m sure Bill is the best one to ask but curious if anyone else has tried this.

It would require a new barrel...you can't make a .223 a 30 cal. Those are single shots and have a hinge welded to them if I remember correctly. You might be able to get a 300 blackout barrel and have it rechambered OR you need to find a 30 cal blank to make a Hamr out of. Bill will be along shortly, he might have an idea for you.

I picked up my Shilen 30 cal 13 twist barrel this week...I need to order the reamer/go gauge so I can get my custom put together.

I imagine it could be rechambered, but without reboring the rifle you'd obviously be pushing a 30 caliber bullet through a 22 caliber bore. I don't know of anyone that rebores to 30 caliber, but I imagine there are. J E S does reboring, but I don't think to 30 caliber. Maybe check with them. Not what you're asking, but they could probably rechamber to 350 Legend if nothing else.

Yeahh, when I said “rechambered” I assumed it would have to be rebored as well. At least in my mind it doesn’t seem like it would be that much trouble. When I bought the gun it came with instructions for sending the necessary components back in to have it converted over to another caliber. So I know at one time it could be done. But I’m not wanting to sink a ton of $ into it, I’m just not sure it’d be worth it. An as far as getting another calibered barrel, I’m not interested in going that route either, again, just don’t think it’d be worth it. In this scenario it’ll be a Hamr or it stays .223 but I appreciate the suggestions.

Finally got my first hog with the Ham'r build. Decent boar that ended up having a broken snare around it's neck and a broken right cutter. Hornady 135 FTX

Congrats and a good boar

I got to range to sight in this rifle on the 100 yd but range need me to qualify in 50 yard first. These are what I did and want to see if that’s alright. WC factory ammo on 16” 1-15 twist barrel. The scope mount I bought was too low so I had to scoot down a little. I was also a little shaky on just front rest.

Didn’t make the 100 yard since it got way too hot and I forgot my spotting scope. I’m thinking I need to try WCs 95 and 110 gr ammo for next time.

Those groups will tighten up as the barrel gets seasoned, as you get the optic set to optimum height and stable shooting platform it will only improve.

I am curious on the 300 HAM’R and understand it was designed for AR platforms, but I am curious why more manufacturers haven’t picked this up in bolt rifles. Any insight into when you think that will happen? It seems like more ammo companies will pick it up once it is more broadly available.

Good question. I thought it wouldn't take long for Ruger to pick it up once Mr. Wilson started offering conversion kits fr the Ranch Rifle. I think the main need is for a couple of the ammo companies to introduce it.
However, we still have not seen the ammo supply lines to fully recover after the shortages of the past few years. Everyone was stuck on .308 Win., 5.56 NATO, 9mm & .45 ACP. Most of the major companies are still trying to catch up.

I drank the kool aid for the 300 HAM'R some time ago, and in my opinion it is the best thing out there for the AR-15. I would like to see some action out of a few companies and I don't mind telling them! Maybe more of us need to do the same.

The key to wide acceptance is ammo being readily available from at least one major ammo company. Trust me I've worked hard on this and one ammo company has been telling me for over a year that's it's on their new products list. I'm confident if a major ammo mfg offers it, guns will quickly follow, but the ammo has to come first.

It's our #2 seller after 9mm, but we are just a small ammo company compared to the major mfg..

Alright. I know everyone on the thread reload so it’s hard to judge how the rifle is shooting with factory ammo. I suspect it’ll change some going to100 yard also. Thanks for the insight.

I built a rifle for my father and all he shoots is Wilson combat factory ammunition. on initial sight in at 100 yards he was getting 1-1/2" until around 50 rounds down the pipe. at that point it creeped down to 5/8" to 1" groups. He was very pleased with the accuracy from a semi-auto rifle. 110 v-max is his projectile of choice out of a 16" 1-15 twist.

I bought a sort of 95 and 110 gr so I’ll see how they do.
