I dont think its flinching, I shoot shotgun slugs sitting from the bench at 100 and get very good groups. (Single shot with rifle sights) And thats some really punishing recoil.you may be flinching when firing if your shooting left, its an unconscious action sometimes your anticipating the recoil?
My shoulder is fine, I do 150 lbs 8 reps overhead shoulder presses in the gym.Have you ever had problems with your right shoulder? I.E: broken collar bone, dislocation, torn ligaments. Not necessarily while shooting, but rather in the past(childhood, teen years, etc).
I'm very accurate with peeps, I have a rolling block rifle in 45-90 that shoots 1.5'' groups all day long with a target peep sight. But it has a perfect cheek weld, a 34'' barrel and it weighs 15lbs, its rock steady.If peeps don't do it then canting or flinching might be it - as suggested earlier. I scope or reddot/Halo most of my stuff now.
At the range I let two people shoot groups with three of my rifles and guess what - they were all shooting to the left, exactly where I was hitting.
That means my rifles are the problem, not my eyes nor my shoulder. This is strange.....
Get a 22 and LEARN TO SHOOT PROPERLY!!!!!!!!!!!!!!!!!!
