I named this board "XCR Heavy 7.62×51mm NATO (.308 Winchester)" since I don't know if it'll come out as a 7.62x51mm or a .308 Winchester. The calibers aren't exactly the same so if someone finds out for sure I'll rename the thread. (My understanding is that you can shoot a 7.62x51mm round in a .308 rifle but not the other way around.)
