Got some nice weather this week, so I did a little shooting. On opening day, hunting temperatures normally start at around 35 degrees in the morning and hit 60 degrees in the afternoon. On a warm day it might hit 70 degrees and at that temperature, my pattern maxes out at 57 yards. So I spend time patterning at that distance and check the results against the temperature. When I shot it was only 58 degrees. At that temperature, I know I can get killing patterns out to 55 yards. I decided to pattern at 57 yards to see what would happen. At 57 yards, I still averaged 101 pellets in the 10, but the actual pattern counts ranged anywhere from 88 to 117. Since a number of patterns started dropping below the 100-pellet minimum, I made the decision to stick with my original 55-yard max and only stretch it out on the warmest days. The Jelly head choke shot slightly better than the H-13 choke, but they are very close. On different days at different distances, I have actually seen the results reversed. It would take a lot of shooting to really verify any difference due to the normal pattern variation that is seen. One thing of note. When approaching 60 yards, I do see a difference in POI between the 2 chokes. In my gun the Jelly head shoots a little lower, so be careful about interchanging chokes at long range.
