The first deer I ever shot turned out to be a knot head.Does were open.This deer was on the run when I shot it. I thought I had a nice little doe. I was surprised when I saw the little knots on his head. I was thrilled that I finally got my first deer.Even though it was my first,if I had of known I would have let him walk.I would never intentionally shoot one. Sometimes those knots are invisible.Ruger Redhawk
