I will be getting a 700 barreled action in 223AI 1/8 twist 24" tube. I am trying to figure out what bullet to use. I am between 75gr A max and 80gr A max. I will be using Alliant AR-Comp as my powder bc that is what I have right now. What would be the benefits of either of them. I want to shoot out to about 600yds or so that is about it. I will be using new winchester brass with cci 41 primers. What velocities are you guys getting?
