Killed quite a few with 75 AMAXs @3100 FPS out of my 223AIs. From 20yrds to over 500yrds. All were DRT. Bullet performed flawlessly, in both trajectory and terminal performance. I do drive 75 AMAXs in a vanilla 223 @ 2975FPS, but havent had the opprotunity to dust a 'yote with it. Im sure it will do just fine....(grin)
