I wonder if you guys would opine on this matter. I picked up a nice Marlin in 30-30, looks brand new but made in 1972. Tried a few jacketed loads and it shows promise of accuracy, but of course I intend to shoot mostly cast in it.
Made a pound cast which shows the following dimensions and the typical short throat: The bore is .3094 and inserting the nose of a 311284 that mikes .3023 is a snug fit but barely scuffs the lead.
I got interested in the 311440 reading Paco Kelley who is fond of this bullet, not to mention any bullet called "the flying fist" has got to be tried.
So my question concerns the fact that I'm going to spec an Accurate mold. Owned a lot of molds by different makers and constantly hear good things about Accurate. Ready to order.
This is a bore riding bullet, what diameter nose do you advise I spec for the mold given a hair over .302 bore dimension? Why I ask is that I imagine that my Lyman 450 will bump the nose when sizing base first (generally casting WW+2%). Should I get .301 and assume it bumps to .302 or slightly bigger? Or spec .302 and hope the bumping is of little consequence? If it bumps to .303 it will engrave enough to possibly stick the bullet.
I would prefer to stay with my Lyman sizer and not get involved with nose first sizing. Also I can increase the nose diameter slightly by changing alloy. But what are your thoughts and experience on this?
