Thread: Copper Projectile Accuracy... Barnes GMX etc..

@Kiwi Greg uses the gmx in a few calibers.

They have a better bc than the barnes and terminal performance seem very similar,I think they are "gilding" metal not copper?

It always annoyed me that in my 308s my short range barnes loads would shoot better than my long range amax loads which were still more than acceptable.
I would have tried 150 gmx as they are cheaper and better bc but wasn't sure the 308 would get them going fast enough to really perform on game.
