I would suggest doing some work at a patterning board to see where your gun shoots.

You may have problems with eye dominance shifting from one eye to the other. I learned that I had this problem when I became tired, my scores dropped in the last few stations of 100 bird SC shoots. Oddly it took taking up bullseye pistol to figure this out. Found my eye dominance shifted to my left eye when I could no longer see the red dot in the scope during slow fire.I was shooting in an evening league after working all day and was not exactly at full energy.

I believe your left eye is taking over and you are forced to compensate for this by winking and using the bead as a crutch.

Try one of those magic dot stick on thingies (or a piece of frosty scotch tape) over your left eye and then concentrate on the target.

You have to be able to mount the gun and shoot dead center without adjusting (crawling) around the stock like a rifle shooter.
