If it is a single barreled gun, kinda like a dueling pistol, then it is most likely going to shoot best with a PRB (patched round ball).
Some shooters will put a 0.030" fiber wad over the powder before loading the PRB.
I shoot three different guns of this type...a flintlock, and two percussion guns. All are .50 caliber. Depending on what i am doing, the loads vary from 18 grs. of FFFg BP to 30 grs. of the same.
