with Llama .22 autopistol(and often hit twice in midair) was acommonplace occurence. 4 years earlier, I'd quickly learned to toss up 1" rocks and hit them in the air with a bb gun. transitioning to .22 rifle, and then 22 pistol, was pretty easy, courtesy of the wax bullets in the .45. They are quite visible in flight. Start with gallon jugs, quickly work down to qt size cans, soda cans, small juice cans, then 1" rocks.
