When I was a teenager, my buddy and I shot thousands of thrown targets with my godawful heavy Model 5 Savage .22. We got the hang of it pretty quick. When I went to Fort Bragg a bit later on, we were put through the Quick Kill program with sightless Daisys. I thought I would be right at home, and was. However, other soldiers were as good or better at it than I was and I suspect some of them had never shot a gun before the Army. Most of us never had a bit of trouble until we graduated to dime sized targets. As Lucky McDaniel said, it's pretty easy to teach and pretty easy to learn. My friend spent 13 or 14 months in the field with a 75th Infantry LRRP company and came home alive. If nothing else, the thrown targets gave him some confidence.
