Hey fellas, I notice on my first dry fire shot I blink, I don't believe the crosshairs move at all. After the first dry fire no blink. I'm curious to if my blinking is a cause of loosing oxygen to my eye and then it starts to squint there after then blink. I also don't think I have a noticeable flitch, I've had times where I forget to take the safety off and i just continue to squeeze easy on the trigger then realize the safety is on. (Maybe that's not a good test of flinching)..I have a light trigger pull, Jewell at 1 lb..also I do hold my breathe before the shot, this is why I'm curious if its an oxygen issue when I blink due to stessing the eye and not pulling the trigger soon enough?? I've read your not suppose to hold your breathe , can't break the habit that seems most natural I guess. Thanks guys!
