I’ve been trying to get a reliable feed in my .300 blackout pistol. It has short, pistol-length gas tube and a 10.5 inch barrel. I found that it wouldn’t work with an at-15 bolt/carrier, but would with an m-16 part. It would seem that either reduced loads or an adjustable gas-block is in order.

I’m loading 300 AAC Blackout using Sierra 200 gr. HPBT Match King bullets. Do you have any updated load data for this? I am shooting a Ruger American Ranch Rifle.
Thank you very much and Merry Christmas!

But the Big Green will still not include heavy projectile and subsonic load data for this or for the 30BR.
