In May 2000 I worked up 460 Rowland loads in a 20 ounce 45acp Patriot semi with the stock 12 pound recoil spring.
I got a flinch.
I would punch my shoulder forward when I pulled the trigger on a handgun, even a 22 rimfire.
I built a 42 pound triple recoil spring assembly, and never shot the 460 stuff again with a 12 pound spring.
Within a month, the flinch was gone.
What does it all mean?
Never shoot anything that kicks that hard again, and wait. The flinch will go away.
