Howdy Ben,
Welcome to the wonderful world of Cap & Ball!
Why not just ditch all the hassle and load up with .44 cal conical bullets? Powder + Bullet + Cap (bullet rests directly on the powder charge), no fuss, no muss! The multiple gas check grooves wipe down any excess powder flakes and make multiple seals in each chamber, ELIMINATING any chance of a chain fire. No need for messy greased wads or crisco or lard or any of that other civil war crap (unless you're a purist, no offense). That's how I've run my Ruger Old Army for years - DEADLY accurate out to 100yds, no joke. Trick is to take your time and start the conical evenly in the chamber; if you don't it can affect accuracy slightly, but when done right is hands down more accurate than a random flying ball (you'll be able to tell by the evenness of the shave ring).
Oldsouthfirearms (dot com) has any kind of conical that you could ever want or need.
Happy shooting!
