Re: 300 blk

I could never get the velocity I wanted with the supersonic rounds and the accuracy was poor with both supers and subs.

Re: 300 blk

What velocity did you want?

300 AAC BLACKOUT is 110 grain at 2450 fps from a 16 inch barrel at 55,000 psi, or 123 grain at 2315 fps.

Sorry, I didn't remember the second part of your question. I have an 8 twist barrel.

That's why I ordered a 300 blk barrel...

The cure for the BLK plague is to simply take a close look at the trajectory and wind deflection charts compared to other AR-15 cartridges. Then look at the various AR-10 cartridges if you're interested in "Long Range Hunting", particularly the 260 Rem and 6.5 Creedmoor.

It is not a good choice for long-range hunting. If you would not shoot it with a scoped-30-30, then you would not want to shoot it with 300 AAC BLACKOUT. We are doing optimized bullets though - something in between the two in the video is the goal.

Re: 300 blk

If you want a 30 caliber hunting round to shoot from an AR-15 look at the new Olympic 300 OSSM. It's just a 25 WSSM necked up to 30 cal, but it gives 308 Win performance.
It's still not a long range cartridge as 150 grains is about the max bullet weight because of the AR-15's short magazine. The only commercial AR currently on the market is I consier "Long Range" the 6.5 Creedmoor in a DPMS LR-65CM. It's good for medium game to 1000 yards . The 300 SAUM was good to over 1000 yards. but (I believe) now discontinued by DPMS and Armalite.

Heres' my 300 OSSM. The cartridges top to bottom are 300 OSSM, 6.5 Grendel, and 223 Rem.
