I've sent mark a couple emails about making me a 10.5" grendel sbr. He posted that they were getting 0.9 inch groups with muzzle velocities of 2200fps with match kings. I know the ablr will have a different muzzle velocity but not sure what it was so I put 2200 in my calculator and I was showing the ablr over 1300fps out to 700+yards which is the minimum velocity for expansion for the round.
So am I reading the data right that a 10.5" will have proper expansion out to 700 yards? The energy is only 500ish so I'm not talking about big game. I'm not even talking about shooting it to 700 yards just trying to figure out if its capable.
