yea that's kind of where I've been struggling. I'm getting 2450 out of my 16 and it shoots sub moa out to 500 with ease. After 600 though it all falls to ish... I was hoping a little extra velocity could get me to 800 more consistently.
According to strelok, at 600 now my velocity is 1600 and at 800 it's 1350.
