The 250 grain .50 R.E.A.L.s actually shoot well in my T/C flintlock Pennsylvania Hunter.
She's a ball gun, with a 1-66 twist, but doesn't seem to really like ball. The above mentioned R.E.A.L, a .54 overpowder wad and 70 grains 3f Swiss Holy Black. Do not forget the wad! The rifling is deep enough to constitute a trip hazard. Without the wad, gas cutting and leading are... bad.
It's actually a little shorter than the Hornady Pennsylvania Conical.
So Your using .54 wad in .50 cal. ? Did you shoot .50 wads and find .54's more accurate ?
