Has anyone used a bullet from a Lyman 446187 (470 gr) mold as a paper patch bullet for 45-70?
I have one I use for my 71/84 Mauser and am considering trying to use it as a paper patch bullet for a Pedersoli Sharps with Black powder.
Cast dimensions of my bullet with wheel weight alloy gives a nose diameter of .433 and a body diameter of .451. I have not cast any pure lead with this mold yet but I'm figuring my as cast dimensions with pure lead should give me a nose diameter of around .432 and a body diameter of .450. I'll be sizing the body of the bullet to .446
I'm figuring that two wraps of .002 paper should put me back up to around .454 for the body. If the paper patch is long enough to cover the bullet nose with the patch up to the beginning of the ogive the nose diameter should be up to around .450. I would then size the body of the bullet in a .450 die giving a bullet with an overall diameter of .450.
I'm figuring any slop on the small side would be taken up buy obturation upon ignition.
What do ya'll think?
Have Fun,
