First post. wanted to show my 40 yard pattern and also ask if you guys think my pattern could improve upon cleaning my gun. Hate to say but never cleaned this gun, used longbeard last year and was ok with patterns so didn't feel the need. Have 265 in the 10" with 8.5 turkey ninja and .568 Carlson lbxr choke. I figured it wouldn't hurt so cleaned my gun after shooting and it was filthy, hopefully it will help my pattern some but I'm ok with the pattern, just trying to optimize my current setup without changing anything as far as equipment goes.
Most guns like a clean barrel. Some don't. It depends on your gun.
I would be more worried about the distribution in the 10". You have a big gap at the 6 oclock and 2 oclock.
