Best place to start is with as many grains as the caliber and work up from there to find the load that gives the best grouping. I shoot 50 - 55 for target and up to 80 for hunting, and depending on the ball or mini used.
Your best bet would be Dixie Gun Works, Track of the wolf or Log Cabin shop. They all carry muzzle loader parts, new and old, and are also all on the web.
Try 50 to 75 grains of ffg. Use the load that makes the least barrel fouling. I use 50 grains in my Thompson Center .45. 50 grains in my Cabala .50 carbine.
