If it's target panic try this. Get a 3-d deer or something similar, and shoot at it. Not having defined rings to aim at may help. You know where you need to put the shot on a 3-d but you won't have the rings to contend with mentally. You'll be shooting at the all brown vital area.
I've never seen a deer in the woods with a bullseye. Once at a petting zoo but that's a diffrent story
