question is, can you run .311 diameter through a .308 bore. I think the mini 30 series has a .308 bore but will shoot surplus .311 bullets.
According to Ruger, post 1993 barrels are .310 to .311 and do not taper down to .308 at muzzle.
Im not seeing any problems with bullets being slightly larger than the bore, maybe increase barrel wear, but that is just a theory.
, but this is also a remington 740
