btw, what exactly is a flinch? Just before you pull the trigger you close your eyes or something?
Ya, that and tending to tense up and jerk the trigger in anticipation of getting punished when the trigger goes off. There's no chance of shooting with much accuracey if you have a "flinch". I've seen guys with a bad case of this. One fellow was shooting some old crap ammo with a .308 at our club and one round misfired. I happened to be watching him and at the pull of the trigger his muzzle jumped up about 6" not from recoil obviously but from his flinch. Its good to practice dry firing once in a while (no ammo) just to see what the cross hairs do when you pull the trigger. Hopefully they'll stay rock solid on target and not jump around when you pull the trigger.
You were asking about bipods back there 'cornflakes'.
