So I just bought a very lightly used Rick Kalnyuik (KAL) PP .50 TGBS .492" adjustable mould. I am absolutely new to the paper patching game and wondered if anyone here has used this particular mould and the boolit that it casts to load in .50-70 Govt? I gather it is designed to shoot as a bore diameter patched boolit rather than groove diameter. I have an original New York Militia Rolling Block, and will soon take possession of an original Sharps conversion 3 band military rifle, and a C. Sharps Arms Hartford Sporter both in .50-70 Govt. Have wanted to try PP'ing for years, but this will finally push me "over the edge". A friend of mine has a Shiloh Sharps sporter in .50-90 so we'll likely try some of these in his rifle as well. Any thoughts and suggestions would be gratefully received.
