I did polish my barrel since I last patterned my shotgun. I'm interested in seeing how this helps my pattern.
I had 195 pellets in a 9 1/2" circle at 40 with my current setup (Indian Creek .660, Hevi-13 3" #7) but the densest part of my pattern wasn't in the circle, so I could probably up that to over 200-210 with a sight adjustment and upping to a 10" circle.
If that's what you're getting with the 3 1/2's, I may just save my $ and stick with what I used last year. I know it is plenty, I just like trying new shells
