The title sums it up pretty well; Ive been flinching on the first shot of almost every group I've with my Mosin Nagant lately. At least that's what I assume is happening; I find my first shot is always a flyer and always roughly 2-3 inches off point of aim, usually to the right, but after the first shot the consecutive ones group nicely. So I'm looking for advice on how not to flinch, I have a slip-on recoil pad on it, and always wear earmuffs when shooting targets so it may be just a bad habit rather than anticipation of pain or whatever.
