On high pressure loads it's extremely unforgiving on primers though. I can only get my supersonic loads to last a single firing before primer pockets become unreliable.

That's perfectly understandable. Really when it comes to .300blk's strengths, they primarily revolve around range and suppression. Personally, within 100 yards a suppressed .45 would probably just as quiet, and do more damage than a .300blk. However, outside of that range, the .300blk really...

all correct, however the top and bottom carriers would never even fire 2-3 rounds in auto. The hammer would drop, fire the first round, the hammer would catch on the auto sear and then nothing would trip the sear so the gun would effectively stop functioning. You'd then drop it to semi auto...

Yes, 11.5gr of 1680 is 950fps. I'm going to bring it up to around 12.0 and aim for 1050 or so. I'm only using this for subsonic.

aubie, I posted this up on 300blktalk as well and many people thanked me for the info they didn't have over there. Accuracy isn't too bad actually, I didn't notice any drop in accuracy from the original length, seems to shoot about 1moa at 100 yards, which is more than enough for what I use it for.

Long time reader, first time poster! I figured I'd post up a video I made yesterday to share one of my new toys. It's a 6" .300blk upper. Originally the barrel started off as a 9.5" Core15 barrel. However with my 9" Arbiter Ti can the overall length was 18", which was pretty long, I didn't...
