It LOOKS so-so with the cannellure and the poly points seem to be offset slightly, on some rounds. That said, in the 4 guns we've shot it in, so far, accuracy is at least as good, or better, than any other factory sub-s ammo. No cycling issues, but I only ever shot it suppressed.
I am interested in this round as well as silencerco rounds coming out. I generally buy hornady 208 grains exclusively because I have found they work all the time which is hard to find in a 300 blk round
I bought some of the Remington 220 when they first came out and yes the problem was ftf. I got so disgusted I sold the gun and waited over a year to get back into 300 blk hoping the subsonic rounds quality would improve
