There's a world of difference between a .410 and a 28 ga.

If you can't kill non-water fowl birds with a 28, you probably shouldn't be shooting.

That said, I was brought being told a .410 is a poor way to start a kid out shooting. It's not enough gun to instill confidence. I started with a 20 as a result and never regretted it. As an adult gun.....it's fine if you show restraint.
