But you have to bear in mind that me as a novice gets really wary when I see information like this
but that said I'm reasonably satisfied that I'll be safe reloading 7.62x51 with .308 dies, etc.
....the general conclusion for using .308 commercial in a 7.62 seems to be a no no.
Apparently the pressures in commercial .308 cartridges are higher, 5600psi vs 5100psi?
Also some other slight (?) difference...
