Thanks alot guys. However I notice that with my 1 particular gun/bullet/powder combo my best accuracy is achieved between 10-20 shots with no patches what so ever. Just load and shoot. After 20 shots accuracy then begins to suffer. I even go so far as cleaning my gun thoroughly, shooting it 12 times, and then I'm comfortable going hunting with it. Then I won't clean the gun until after hunting season. Have I developed a bad habit that needs to be broken? My hunt load is a .50 cal. 240 gr. Swift A-frame with 150 gr. pyrodex charge (pellet) and a Win. 209 primer. Gun is a Knight Disc. Thanks for all of your help.
