My 13 year old son did it just last year antelope hunting. He had a choice of several rifles to use and picked the .300 Win mag which he had never shot before. At the shot the buck dropped in his tracks and I was watching thru the binos. What I didn't realize at the time was the scope had clocked the boy in the head....right between the eyes, on the bridge of his glasses. Nasty looking wound. Apparently several years of shooting prairie dogs with much lighter kicking rifles had made him a bit complacent about how he held the rifle. He learned quickly from that point on to respect that gun.
