Ditto #5 and I'll add a reason.

They go bang and are accurate out of the box, at least the few I've had were. And if the mood ever strikes that you want to upgrade it with a better trigger or barrel or whatnot, you won't find another .22 rifle with as many drop in accessories as a 10/22.

Gunnery, gunnery, gunnery.
Hit the target, all else is twaddle!
