Some time ago at a shooting club I was a member at, a fellow member was showing off his new AR-15. He checked his bag and had only one round for it. I told him he'd better make it count. He challenged me to make it count, instead. I told him I'd put it through an 8.5x11" piece of printer paper at 200 yards, standing. He set the sights to the 200yd setting, put up the target, and gave me a magazine with the one round. The the amazement of a very old-timer who was a spectator, I hit the paper. I even called the shot slightly right of center. It was no fluke, I hit targets that size in the Marines regularly.
So yes, what you describe above is not particularly amazing.
