I'm sure someone out there has your problem since there is a plethora of problems when it comes to shotgunning. Do you pre-mount? I think most people who pre-mount check the bead initially. What you don't want to do is check it once the target has been launched. This is called checking the barrel. I know I do it sometimes and it usually results in a miss because it usually happens right at the shot. Either that is happening or my non-dominant eye (left) takes over. I'm not sure which?? It happens more when I'm fatigued. It may have more to do with concentration than anything?? Anyway, I feel your pain.

Socialism is almost the worst.
