Just bought a older Pedersoli Kentucky pistol and a H & A underhammer.
Pedersoli - is stamped 44 cal - and a ball gage measures .440+ (top of lands). I have some .433 balls and some thin patching (.007 or so). Might work, but need a little less rain...
Underhammer bore is measuring @ .350
Thinking of .429 and .340 diameter balls.
Should I go for a .424 diameter mold?
Thanks
