Cirus,

Mine is the same as yours and I use the .530 balls and a .015 patch. Some info I have states a max charge of 120 grains of 777 ffg with that ball and a .020 patch for a muzzle velocity of around 2000 fps.

I bet that .020 patch would be tough to get down the barrel. A .015 is pretty tough with a dirty barrel.

Civil War confederate guerrilla sniper Jack Hinson made hits on union soldiers up to 1000 yards out, using a muzzle loading rifle custom built for that kind of shooting, loaded with Minié balls. Admittedly, he typically fired down onto troop transports from high up on bluffs lining the river, which would have had the effect of reducing his bullet drop over the range; but those would be hard shots even with a modern centerfire today. It seems to me that shooting that kind of bullet would at least increase your hit probability, and maybe even extend your range a little bit.
