While I understand why you wrote all the other stuff, THIS is the key take away that aligns with why the original poster went with the .22 caliber. Some people aren't going to research anything, or train, or do any of the stuff they should do. For some, it really is the .22 or nothing. And we all know the .22 is better than that nothing. I'd do all I can to convince them otherwise, but in the end it's their choice. It might not be a logical choice, but it's still their choice. As long as they have something, it's better than nothing.
