Appreciate it everyone.
If one of these where what he saw, they won't do what he wants. He wants to shoot his rifle to 1k, and given the 20MOA rail and scope he has, the ballistics tables indicate his scope will bottom out at about 975. Of course he can use his reticle to get the extra MOA or so, but I think it's bugging him a little and a faster bullet will let him say his rifle can get to 1k.
He shoots Federal 175 SMK and it groups really well with his rifle. I'm going to buy him a box of Hornady Superformance Match 168 grain for him to try if and when I can find one.
