I've been blaming my AK's sights for my shitty groups, but I'm starting to think it's me. I just don't understand the concept. When I'm looking down the sights I can line everything up perfectly, but it's difficult for me to shoot <5" groups because at 50 yards the front sight post covers the better part of my 12" targets. Plus when I'm shooting my 10/22 with a 9x scope even the slightest breathing movements can move the crosshair ~3" across the target, so I just can't fathom how someone can be that sure of their shot with irons. Any advice?
