I finally think I have my ROA dialed in????
I was getting 2-2 1/2 inch groups shooting from a sand bag at 25 yards with the following load:
30 grains of Goex 3f BP
10 grains of cornmeal
Sagebrush lubed wad
Hornady .457 ball
CCI #11 mag cap
Bore snake down the barrel after each cylinder.
Changed to Speer .457 balls and CCI #11 regular caps and my groups went to 5 inches.
Would a different brand ball and cap make that much difference??
What kind of accuracy with what loads are you other ROA shooters getting?
