I went and shot at 100 yds yesterday and had an interesting 4 shot group... 4 in high dead on left and right, 2 in high dead on, 3 in high dead on, 1 in high dead on in that order. No movement left or right just up and down. Im questioning now whether the 777 pellets im using are rubbing off some of their powder while in the box. Seems like the powder load is not consistent. Has anyone experienced this before? I am cleaning the bore between shots with no. 13 and then 3 dry patches. Any advice would be helpful! thanks
