Long story short:

I'm trying to conserve my stash of 175 SMK and Varget for my son the rest of the season. I want to shoot a 600 yard F class this weekend with him. I've got just enough Black Hills 168 SMK box ammo to shoot a match (+sighters). They have been very accurate in my rifle out 400-500 yards. I've just always shot the 175's for longer range.

Wanted to hear feedback on people that might have used them in for 600 yard matches?
