IMHO, if people spent time getting the stocks of the
bigger guns CORRECT FOR THEM, this would go part
of the way to reducing felt recoil.

Then if recoil was still an issue they put a small amount of
money into a Recoil Reducer, Decelerator Pad etc etc, this
would further help.

Also, in general people go for "hot" loads whereas if they started
off with slightly less powerful loads and work up, they would then
find they could handle the rifle better.

And lastly, if people practised shooting from a standing rest
instead of a bench rest, they would not end up with nearly as bad
a fear / flinch.

When I first purchased a 30-06, it kicked the shit out of me from
a bench. I can now shoot up to 600 Nitros without a problem
by fixing what was wrong.
