Charles,, your last comment is like saying I caught my limit of big fish using a yellow bucktail jig once,(25yrs ago)and I'm gonna kept tryin till I catch'm all again.
Well,them fishes don't like yellow no more cause it's dry this year.
Maybe dump the crisco. Try bee'swax or Alox or Bear oil? Spit?
It just might be the combination of lube vs. charge that's causing your problem.?Packin? A spring or nipple?
Maybe try t7 or swiss?
Point is experiment. Maybe dump them leather patches and try cloth for PRB,or sumething besides "chapstick"(the yellow stuff in a tube) fer shootin.
I can tell ya right now, upgrading to top line powders beit true or faux will increase your accuracy and decrease your cleaning time.
Whatta ya wanna use for the hunt? $ 8.99 or $ 17.99? your choice,,,sportsmen.
