Aim small... Miss small... I think it has more to do with "focus" as apposed to your shooting!? I tell folks, I couldn't hit water, if I fell out of a boat. 3-D shoots are fun for me, but I rarely if ever score well, lol. I have trouble shooting around other people. (Family, friends, or strangers, makes no difference) I have a deer target in the back yard, some days I'm in, some days I'm out. (Some days WAY out!)
If I'm stumping alone, I usually can't miss! Lol! Hunting...?? If I shoot, I usually end up dragging something! (unless I do something TOTALY stupid, like attempting an awkward shot. Then I usually end up missing by FEET and the deer was never in any danger anyway!)
Try covering your target with a piece of paper, or cardboard. Put a little dime sized dot on it for a spot to focus on. Let us know how you do!
