I got a couple of bad misses by aiming over the protective wings instead of the sight post when I first started high-power (30 caliber "big bore") shooting in the rapid fire stages. Concentrating on recovering my sight picture after recoil, and was concerned about finishing the stage before the cease fire. Finally realized that "rapid fire" didn't mean shoot as fast as you can. I wasn't hitting anyone else's target, though. Saw the berm puffs and figured it out and added that to my mental "each shot" checklist.
If the range had been damp so no puffs occured, I might not have figured it out for a while.
Hate to admit it, but it happened.
Part of the problem was I was wearing a very stiff leather shooting jacket for the first time and its thickness and lack of flexibility threw off the effective length of pull for the rifle, so the first "natural" sight picture I would get was over the right wing of the protector, making my POI low and left.
Duh.
Well, as the saying goes, "The match goes to those who can solve their problems best."
