A .22 is excellent for learning, and the right place to start. A heavier calibre is more optimal for downing a human being, but that comes later- accuracy first, then speed, then power. Frankly, if you really need to do serious damage, it's hard to beat a shotgun at close ranges.
And a .22 is not to be despised- you really would not care to be hit in a vital area with one.

Thank you for all the information. You guys have all been very helpful. That's a good idea to practice with the 22, but get a larger caliber gun for the bad guys. :)
