so i was looking into getting a a long range precision rifle with the .308 calibre but curious if i can just load 7.62 in it? reading around i have decided .308 match ammo only, no junk. but i'm curious as to nato rounds compadibility. i know you can fire .223 and 5.56 in a 5.56 chamber but only .223 in a .223 barrel so there are some differences. it would be awesome if someone in the know could link or write a small faq about these rounds. i would like to get into reloading but even hours of reading i'm still having trouble getting into it, oh and the funds.
