Hi all. So I purchased a complete upper in said caliber and come to find out it is a .308 barrel. Since probably most all of you have more experience in this matter, have any of you shot the surplus .310-.312 ammo in a 308 barrel? That was the main reason for getting it. I have made up some using 125gr Nosler ballistic tips but that defeats the purpose of less costly ammo. I'm guessing they'll work but wear the barrel out sooner? Thanks for any experience knowledge.
