I love peep sights. Have them on nearly all my levers, and working on making it all (have some new ones).
Kinda like Smokey. Been shot at twice. Once as a killed squirrel hunting/never knew where it came from. We were in a hollow and it was over our heads. Whomever it was may not even have known we were there, of coulda been someone trying to run us off.
Other time was deer hunting in the CA mnts. Guy that shot at me/deer trotting towards me (his buddy had run it up out of the canyon) KNEW I was there! He had waved to me as I walked out on the ridge. I heard his buddy, and deer, so waited to see if I could get a shot. The shooter was ~400 yards from me. Just before deer went by me at 10 yds, the guy shot. I stuck behind the tree for a min, just long enough to take a breath and get real calm. Next thing I know I have him in the crosshairs, centered on the Budweiser can in front of his chest, and I am taking the creep out of my 1 3/4 lb trigger. Fortunately I caught myself and stopped. He wasn't worth killing (but only barely), and probably never knew how close he was.
