I worked these S spruce up over 30 years ago. I shoot them just about daily. I have never killed an animal with....whoops, a couple squirrels here and there and maybe a snake or frog. I got them from 3 Rivers and one of the twelve was no good and about 10 years ago I broke one stress checking them before shooting. It was beat up pretty bad and had wore a judo for most of its life. Good stuff!!
