I had such a bad flinch right handed that I had to start shooting left handed. It was that or quit. I had stopped shooting for six months and the flinch was waiting for my return.
I made the switch with a .410 to remove all recoil issues. Easy to do for me as I had learned to throw and bat from both right handed and left handed in baseball. After a few months I was once again breaking mid 90's in practice with the .410 in Skeet and 88-92 in trap at 16 yards.
After a couple years shooting left handed I went back to right handed. It took less than two weeks to be comfortable right handed and the flinch was gone for the most part. Maybe once in a hundred. Not once in five shots like before. Most times I can withhold fire when I flinch and just shoot the bird a bit later. When I had my bad flinch problem I looked like a drunk, with a bayonet, when it happened. I did not mind the laughter but it was becoming a safety issue in my mind. Now my flinch just makes me look like a old fellow who can not catch the bird. Hang in there your shooting will become smoother and more consistent.
A release trigger might have been easier, Im guessing.
