so if you building from scratch or rebarreling you could just as easy have a faster twist 7.62x39mm ,you could easy as use a .308 cal barrel too.
I mean isn't that the same as the AR crowd are doing with the .223????? poking fast twist barrel and running heavy pills which really makes it almost a different cartridge...funny thing is they are really just getting a .22 high power savage type result LMFAO.
