I'm a bit ol' fashion, I reckon. I use the rammer that came on the revolver
My 1860s and NM 1863 get 25 gr FFF and a SOFT, .454 Round ball (thats at least 2 thousandths over sized for the chamber).
My Dragoon gets 40 gr of FF and the same .454 ball.
best practice is to charge a chamber with powder, then ram a ball home. repeat.
A tight-fitting (soft lead, oversize) ball is all that is needed to completely seal the chamber.
I add a over-ball lube to keep the bore-fouling soft.
Cleanup with soap/water followed with a water-displacing lube (I use WD-40).
Been doing it this way since I was a boy.
Proper fitting caps, and your GTG.

Slim
