I had an NC-Star LER 3x9 scope crap out on me. It was installed on the rear sight base of a Finn M39.
I was hunting whitetail in some rough country. As I was climbing down a hill, I took a tumble (no round in chamber) and whacked the rifle hard as I fell. I was climbing down to field dress a doe my dad took. When I finished gutting her I saw a buck approach. I think the doe scent on the doe and me was twitterpating the buck.
The scope zero was all over the place after that. I had a 40 yard shot at the buck and missed 5 of 5 shots. Dummy just stood there. I finally bagged him by sighting down the barrel for a lung shot.
