The only reason I could not use the wet patch more then four times, is they kept tearing when they meet with the cleaning/loading jag. Another thing that has helped me tons is all the tips I got about trigger/finger control. I have been really concentrating on that, and it had tightened the groups.
Once all the weeds die out along the shooting lane, I can start shooting further. With the bad knee, I never went in this spring and summer and wacked them with my brush hog. So they kind of grew out into the lane a little. The first good frost will take care of that.
