I agree the #5 mags look the best, but the #4's impressed me the most. 145 pellets for 61%. The #5 Magnums we 189 for 58% and the #5 HV was 150 for 50%.
I'm gonna try the #4 magnums next, I think they will be the tivket. Nothing against #6 shot but I'm saving them for last. I just wish there weren't so many gaps.
