what is a flinch? it is an involuntary reaction to the anticipation of being contacted by something... whether in the forhead or the shoulder or even powder from a revolver hitting ya in the face or worse yet the eyes (eye protection kids)... therefore... you want to get over it... it is all mental... "There is no spoon".... you must convince yourself that there is nothing to fear nothing is going to injure you.. all you are gonna get is a punch to the shoulder...

now to the 2nd part.. why are you catching a scope in the melon... either 1) it is too close to your face or 2) you are not following through.... when you squeeze that trigger and it goes off your whole body should move with the recoil... your cheek should be glued to that stock and move with it (this isn't 100% possible... inertia)... something you have to work on to improve and then back to #1... eye relief... most scopes have plenty, at least better quality ones... i only get close enough to get an entire sight picture in the lens... i don't "choke up" on the bat anymore than i have to... you might get hit in the hands by the baseball coming at you at 90 mph.... see what i am getting at.... so #1 proper setup and #2 proper form workin in conjunction will help you concur the flinch once the danger is eliminated....

happy shooting...
