Yes, they Do seriously, HELP on "Flinching" with, a Shotgun, in Competitive, Clay Bird Shooting.
It was, Give Up, the Sport of, Trap Shooting or, Change to a Release Trigger for Me, in the late 1970's with, a Model 12 Winch.
What "happens" IS, If you are "Off the Clay Target" Your Mind says DON'T Shoot, therefore, you'd, Flinch ! ( I Don't Believe, Flinch was From Recoil )
After a Few Months of, Learning How to Use, ( Control ) a Release Trigger I became a much Better Shot ( Picking Up the 2-3 Birds, that I would Lose / miss with,.. a Pull Trigger, by Flinching !
I Sold my, Un-Braked, .338 Win Mag Rifle and went to, a .270 WSM ( 1 1/2 Lb Trigger ) shooting, 140 gr Bergers at, 3,200 FPS ( My Field Rifle, "Shooting accuracy",. Improved, greatly ! ) and the Elk Died,.. just as Fast as with, the .338 W M. ! ( The .338 WM "Flinch",.. WAS from, Recoil ! )
Now, I shoot, a 6.5 Creedmoor, Tikka, w/ an, Elay Prec. 1.25 Lb Trigger with, 130 gr ELD- M's @ 2,800 FPS,. Braked ! ( REAL Pleasant, to Shoot !! ).
I HAVEN'T, "Flinched",.. SINCE !
