Ok, I have decided I need to try PP in my muzzleloader. My bore is .458 but my rifle likes bullets in the .455 range. The picture has three bullets I am going to try. First is a 457121PH ( lyman whitworth) bullet. Next is a .459-405-HB ( lee 45-70) bullet, and last is a 454-298M (Lee 298 gr mini) All were poured from soft lead.
I first sized the bullets to .452 and then I PP'ed them. But they were measuring .458. I used tracing paper that measures .002 and I gave them two wraps.
Since my barrel likes .455 what I did is wrapped the bullets and ran them through the .454 sizer. I also ran another batch through the .452 sizer. I am planning on trying these when it is warm enough. I know that the paper is supposed to separate at launch and sizing like this will not help, but how much will it hurt? this rifle is a gun that I shoot out to 300 yards. Ron
