Okay I went back out about an hour later and took ONE shot with Pyrodex P and it grouped perfectly with the first 2 shots!
Loaded up jim shockeys gold,Let it cool between shots, took my time, first 2 shots on a nice cool barrel did perfect again! Then the third shot on a hot barrel did the usual.
Cooled down once more,
I am a happy camper!!
Shots 6 & 7 were with home cast .490" round balls. They actually felt a little more snug in the bore than the swagged balls I was previously shooting.
