what a difference
shot some round balls from my TC Greyhawk today for the first time, I started out with 80 gr. 2f goex .15 prelubed patch and .530 ball. shooting 50yds my group was about 4 inches, not good. Tried a different patch an old cotton patch that I lubed with CVA patch grease, stuff is probably 20 years old. Powder and rest of load the same only now I had a group size less than an inch. I never would have guessed that the patch could make that much difference. Anyone ever have this happen to them? Something so small make such a difference.
