I've had two chainfires in two different .36 cap and ball revolvers. The common denominator was a damaged, out of round mold that produced balls with uneven surfaces. Crisco does blow off after the first shot, but it does leave behind a film that can be useful. With that in mind, I started going right to the "film," using the vegetable spray PAM over the balls, and on the cylinder pins of my Remingtons and Colt Paterson (they do not have grease grooves on the pins). PAM works, but you must completely clean the gun after shooting.
