RE: flinching problem
Alot of guys have "shooters flinch" and never get over it! I had it till I bet I was about in my mid twenties. You are not scared of the gun or you would not shoot it. But your eyes and the part of your brain that controls your eyes are. Its self defense for the eyes, they want to shut because they think they could get hurt! And as with your case they have proof! Now fallow these steps and you WILL be able to overcome it!
This may sound anal but start out with these small steps and you can do it. It will take a few days but do this exercise and you will be shooting with your eyes wide open!
First you have to have a BB gun with a scope, but iron sites will do. You and I both know that a BB gun will not kick so when you shoot, force yourself to keep your eyes open. Don't worry about hitting the target but just try to squeeze and keep your eyeopen. Once you master that at that level you will feel better. But do not go to the next stepuntil you can shoot your BB gun with the eyeopen the entire time! Remember, you have to be able to pull the trigger fully with your eye open the entire time be fore you are done with the BB gun! Sounds juvenile, but if you cant do it with a BB gun then why are we even talking about a regular gun? Right? If you can plink off a few shots with a BB gun, then put it away before your friends see ya and move on to the next step!
Next you get out a .22 and go to wal-mart and buy what is called CB's. They were made in my opinion for the late night out of season coon poacher, but that is a different issue. But any ways, you get the CB's and shoot them. A CB is a 22 with not hardly any powder in them. They are not much louder then a BB gun, in fact alot of guys shoot them in town all the time to take care of rat and other rodent problems. But this is the next step. You shoot them, they don't kick and the report is low so it will be easy to learn to keep your eyes open with them if you first mastered the BB gun.
Now when you get the CB's mastered you go and get some 22 shorts. work on them the same way. Don't worry about the target, after you master the eye you can master the bullseye! Force your self to keep the eyes open. Once you keep your eyes open, you can work on the target! After the shorts get some longs and do the same thing. This will take a few days, don't try and cram it in one afternoon!
After the 22's are done move up to your 410. And I will not say everything twice but you get the pattern right? Buy small short 410's and work on them. Also wear earplugs, this will help with the sound which will help your eyes. This is alot of work, but it is a good training method that worked for me! Now get out your BB gun and get started!
