Request for advise: I hope to make a smooth sided paper patching mold for a .45-70. Basic .458 dimensions from slugging. Chances are I'll be using regular coping machine paper with which to double wrap. What do you more experienced guys think will be the best mold dimensions & weight? I usually size the wrapped boolits at .459, with a touch of "Bore Butter", before loading. Now instead of doing this with one of my other standard molds, I'd like to have a dedicated PP'ing mold. Buffalo Classic ~ 500 yard gong.
Thanks, 725
