As mentioned, the 155 AMAX is not even in the running aerodynamically speaking. If your going light, shoot the 155 Scenar or the 155.5 Berger. If your going past 900 yards, might want to consider the 178 AMAX or 175 SMK for transonic stability.

I shoot 155g Scenar over 46.5g Varget, F210M at get 2860-2880 from a 22" custom tube. The Scenar/Varget combo is very easy to load for.
