I don't have the experience of a lot of these guys when it comes to extensive testing and patterning of different chokes and loads, but I did load my first shotshells last Spring. This pattern was shot with my first attempt at shotshell handloads. TSS 9x8, Indian Creek .550, charles daly youth semi auto 20 ga. Taped 40 yards. I had a pic of a more open choke that gave a more even pattern, but can't seem to find it now. I got 180 in the 10" with it, and it was a much more even spread. Guess I'll have to shoot a couple more patterns this spring.
