OK. Here's the first and last time I shot at 100 yards . The first center group had the better wind conditions . The next groups were shot fast in light gusting winds just to get some shots on paper . I used 18gr fx badged jbs pellets in the 880 range, back when I was still learning to tune and index . I have no doubt I could do better and wouldn't have expected great groups with my PBs in the same conditions. We seldom get a calm day and makes even the 30y challenge tough . I needed to work on my hold off for wind and now dial in instead of using holdover at distance.
The group sizes were 2.32" , 1.73" , 1.91", 2.01" and a best of 1.20" 3 shot group . A 1.83" average for 19 shots . A golf ball is 1.68" . So .154 " over a golf ball .
