I like to tell myself I don’t flinch. But I know I do, sometimes. Especially with that old trigger exercise where you slooooowly squeeze until it fires. I was always told that if done correctly, it should surprise you. And it does.
Sometimes it also gets me when it’s a nice, quiet range and I forget to put my earpro in.
Truth be told, at times I wish I did. Guess because I grew up getting shot at as a child and being around guns as a child, plus the training in the service. I rarely do flinch, might get pissed or throw a punch or something.
I tested for flinch by using a revolver, preferably with a swing out cylinder. A friend loaded it with 1 , 2, or 3 rounds, spun and closed the cylinder and handed to me. I then watched the sights when the hammer fell. If the sights move, you flinched. Did I flinch? Sometimes, but I’m getting better.
I do the same, but, I put 6 rounds in my pocket. Various strength, and a couple of specials mixed in the magnums. With 1 hunting load in the mix. All from the same manufacturer, so the all the brass is similar. I dont look at the case, I just put them in the cylinder, give it a spin, then close it. You might be getting a 110 grain, powder puff .38, you might be getting a .357 mag 180 grain deer load, you might get the fast and loud 357, 125 grain flame thrower.
