Ok, I know many of you will tell me to look at other manufacturers but I look for Lee for a few reasons, one being affordability. That being said, I have two Mosin-Nagant 91/30's. I have slugged the bore of both and they both have a bore diameter of .312. I have looked every place I know of and can't find a Lee .312 or .313 lube sizer kit. Does anyone know why they don't make one? They make a .314 but that would concern me of leading my barrels. All of my manuals state in the data section for 7.62x54R that the bores of the rifles coming from the former Soviet Block countries are usually .312 diameter. So you would think Lee, among others, would make a lube sizer that is .001 over the bore diameter. Does anyone here use the Lee .314 lube sizer for their mosin rifles with a bore diameter of .312? If so what kind of results do you get? Thanks in advance for any help you can give.
