What do you thin of my Sharps bore?

Mind blown again. So when I fire a .515 bullet out of my .50 cal Maynard it leaves no residue (leading) behind because it's humping along real slow?

Steve,
From your pictures it sure looks like lead to me. Can't imagine a bore being that rough having soft lead bullets shot through it, Besides velocity, pressure will do the same thing. Say by shooting large charges behind vastly oversize bullets.

This weekend I had a chance to go and try out some "Bobtail" bullets that Bob Anderson was kind enough to send me. This is, as I understand it, a rendition of the Frances bullet, with a ring tail for accepting a paper cartridge tube.

I did not feel like making a dipper for these test bullets to keep the nose free of lube, so I just dip-lubed the entire bullet. The cartridges are made from standard computer paper using a variation of the Ordnance Manual pattern, truncated to fit my Pedersoli chamber.

Bob cast these using 1:3 wheelweight:lead alloy. I sized them to .542 using a Tom Crone sizing die. I used 40 grains 3F Goex. Cardboard wad glued on top of the powder to keep the powder at the tissue end of the tube. No filler.



On this picture, the hole near the bottom of the paper is a staple hole.

This looks very encouraging to me. Hard to say with only 18 shots, But even my worst target looks to be about a 4" group, and the rest are 2-3" groups. Next I'm going to experiment with a Lee Rapine copy mold I have, sized to .542, and then I have some bore-riding bullets that Larry Flees sent me to try also.
