I bought a Beretta M1 Garand receiver from Tradex a while back and am now getting motivated to start my build. However i was warned by a friend that some where .308 and some were 30-06. HE is concerned that i may have a .308 receiver. How do i know the difference? I would prefer to make it .30-06 but i will do whatever the receiver is if that is the case.
