So, to treat it straight, the .410 isn't the best choice for a young learner. The guns are typically full choke, which leads to a lot of frustration beyond what a kid should have to tolerate. It will work better, of course, if the parent cuts the stock to a proper fit, and has a gunsmith ream the muzzle to Improved Cylinder. Then, work with targets at fairly close range.
The whole idea is to build confidence by providing a challenge, but a challenge which can be met.
