Dilly have you tried a lube with tallow? In my 54 I use a .530 ball and pocket drill that is .021 with just touching slightly firm mic pressure, and my new trial of beef tallow and 20% bees wax. Man how easy it loads as good as mink oil from T.O.W.! Pure mink oil loads more difficult with .019 cotton patches. And the better part I finally tried shooting with out swabbing between shots which I could not do with just mink oil without a mallet to load with. After 5 shots no wiping I tried a patch with just mink oil and almost got stuck half way down, with pounding it seated….went back to tallow and loaded normaly…. No blown patches at 85 grs. 3f schutezen.
