Okay, here's the plan...
Mosin 91/30 has these dims.: bore (lands), .302; groove, .313; throat, .316
Wanted to use Lee C312-185-1R for PP boolit, but have since read several posts on this forum that nose dia. typically runs .300 to .3015
Not a huge obstacle, can get by it by "beagling" or lapping the mould, right? But if I'm going to do that, why not choose one of Lee's .309 rifle moulds from the same approx. wgt. range? Main advantage would be little or no sizing of the body portion.
Alloy is WW with a little added tin. Harder alloy is not an option.
Please post your thoughts on this. TIA ,
