With the 54r .311" is the norm but some old Mosins will slug out at .314 or 15 depending on the amount of use they’ve had.My issued '39 Izhevsk 91/30 is .313" but still shoots well enough with standard .311" milsurp, whereas my unissued '44 M44 carbine is pretty much on the money at .311"

More than a vested interest in 7.62x54r!
