This might have been better posted in another category, but since single-actions are the most often used handgun for big bullets, I put it here.
A tip to manage heavy recoil:
My dad taught me this 50 years ago and I still use it today. This works for new shooters as well as experienced ones who develop a flinch. I still do it now and then just to keep myself aware that the blast and kick is not going to hurt me.
Load the cylinder with 5 empties and 1 live round. Gently spin the cylinder, or let a friend do it. From the shooter's perspective, he cannot see anything but the rim of the cartridge. He doesn't know when the live round will come up.
Take a two handed hold and aim at a small bullseye target 25 yards away, or some target that takes extreme concentration to hit.
Cock it, squeeze it off. If it doesn't fire, you know if you flinched or not.
Spin the cylinder again, repeat.
One or two sessions of this at the range and you or your student are cured of the flinch. It's a good excercise for even well-seasoned big bore shooters.
Another variation to this is that the instructor loads all cylinders with empty cases and lies to the student, telling him there are some loaded and some not. Now the student is hyped up a little more, expexting a probable boom. If he flinches, he knows he flinched, and will eventually learn not to.
For rifle shooters, a bit more extreme exercise, is to learn to shoot a flintlock. If you can shoot a flintlock offhand and hit your target, you can shoot any rifle ever made. To hold on target while the fire is transferred from pan to charge, takes real skill. This is better done with a dull flint so you won't get instant ignition.
Class will resume after the break.
