RE: flinching problem
 

Does it happen when you are hunting or only when your at the range?

I never had a dlinching problem, but I did get a fair amount of moon shaped cuts by my eye when I was younger.

If it only happens at the range, you can get a rest that takes away the kick. I think one is called the "Lead sled". You can put weight on them that obsorbs all of the recoil. They can be pricey, but they are worth it.

I have a homemade device that I use to save my shoulder while sighint in multiple guns. It is a large steal plate that has a small steal strip welded onto the edge of the plate at 90 degrees. I then screw the plate into my shooting table. When I shoot I put the but of the gun against the metal strip that in turn is up against my shoulder. I don't get any kick from the gun when I use it.
