I was having dinner last night with my son's father inlaw when the toppic of guns and shooting came up. Apparantly in the mid 1960's he was a "sharp shooter" in the South African Army and qualified by shooting a 4" group at 500 meters using an FN rifle in 7.62 Nato with open peep sights. Sounded like a feat of remarkable marksmanship. I could see a scope sighted rifle off bags on the bench doing that kind of grouping, but open sights and prone position left me wondering on the feasibility? I did not challenge his claim, only told him that was some incredible shooting. Any thoughts from competive shooters?
