Got a very bad batch, Nov 2019
I have used several thousand of this particular round without any issue before my latest case of 1,000. The batch I got in Nov 2019 is flat out dangerous. Bullets can be pulled from the cases by hand, primer pockets are loose, and I have over 30% failure to fire. Some of the rounds feel overcharged. I don't know if S&B crimps .300 blackout, but if they don't, i suspect all of this brass is oversized in very critical dimensions. Primers and bullets are literally just falling out. Cons: Loose primers
