Never knew why I flinched, all I know it became that bad all my Buds used to take a step back each time I mounted my gun to shoot.
I could see them in my peripheral vision take the step back all 4 of them and then proceed to wet them selves laughing, I would flinch 8-10 times every 25.
It was funny to us all at first including me but after a short while it became a costly venture to find a cure for me.
I tried everything but a Release Trigger for approximately 2-3 years, new guns, new stocks, softer shells, different holds on the Trap, you name it I tried it all except a Release.
I was shooting the 1999 Grand and finally gave in and had Phil Crenwelge install a Release-Pull, he tried to convince me to go Double Release straight off the Bat.
I believed it was going to be hard enough to get my head around a Release-Pull let alone a Double, fast forward to 2010 Iowa State and you guessed it flinch started on my second in Doubles.
Luckily Phil was on hand and a Double was installed, took to it like a Duck to water and have not had a flinch since then.
I know a Release is not for everyone, I never tried to analyze the problem other than I knew I had a bad flinch and did not know what caused it, didn't care just wanted it gone.
It often amazes me what the human brain can be trained to do without much effort, we often over think things and convince ourselves "It's just to hard"
Believe me if you need to change a little effort will have your brain working just the way you want it too.
If you stopped me now just before I call my target and asked have you set your Trigger, I would have to look and see as it's a total subconscious action for me.
