For .44:
.454 cast or swaged RB, eve if mfr recommends .451.
2F Goex. All the chamber will hold and let you seat a 1/8" felt wad so that it does not interfere with the ball centering in the chamber mouth.
Lube is Gatofeo formula, soaked in wad.
Same for .36, kust sub a ball diameter that will leave a ring of lead.
This recipe will shoot well in any gun i own except one ASM 2nd model Dragoon. It is easy to load in the field, and fouling stays soft.
My ROA's will cut one hole with this at 25 yards. You have to back out to 50 yards to get meaningful variations in group size.
