I have three rifles that should - in theory - measure .311-.312:
SMLE = Groove diameter .314
Mosin m44 = .315
Mosin 91/30 = .3135 - .314
So, can I just size .316 and use the same bullets for all three? I would be using hard alloy (basically linotype) and I am concerned about causing too much pressure. It would be about 2 - 21/2 thou larger than the groove diameter in the 91/30.
Should I be concerned?
