I had a similiar experience with a lever action rifle, when the bullets werent chambering correctly, and a puff of warm air would hit me in the eye, making my close my eyes. Gun on its way to get looked at my the mfg. After that, I started closing my eyes almost every time I pulled the trigger. What I did, was a to take an empty rifle, pull it up to the target, look at the target, and try and forget about the rifle, forget it was there, then pull the trigger. After getting used to it empty, then I put rounds in doing the same thing. Forgetting about the gun, and focus on the target. Actually improved my aim! :-D
