I just purchased 240rds of 147gr Armscor 300blk ammo. I read positive reviews on the ammo, so I thought I should order some and give it a try. I looked at the brass casings and they have been annealed but the case necks are all messed up. It's like the brass was cut down but never trimmed to a uniform length. You can see it with the naked eye, no calipers needed. I have used .223 armscor in the past without issues, but this stuff just seems like it was loaded with really loose QC standards. I have yet to use any of it, but even if it doesn't blow up my gun...I will spend a few cents more per round and get something much better.

What do you 300blk shooters use for good ammo for training purposes?
