I want to buy a 50 bmg. The purpose of the rifle is to shoot as far as possible at steel targets and ocasionally hunt big game at extreme distances. I have a lot of expirence shooting long range but no expirence shooting a 50 bmg. Is it possible to buy or build a 50 that will shoot under 1 moa? I was looking at purchasing an accuracy international AX 50 but have not found any accuracy reviews? Is there any other rifles i should be looking at or am i wasting my time thinking i need a 50 for extreme long range work and stick with my 338s?
