I have a friend who lives in the country. His wife has had several close encounters of the "critter" kind. He is not gun-savvy (by his own admission). He asked my opinion about buying her a .22 rifle to deal with future critter incursions. I cautioned him about bullet carry (they do have neighbors) and suggested a .410 as an alternative. She would probably have a better chance of hitting her target and less of a chance of hitting, well, a "non-target".
I welcome any comments on my recommendation as well as specific model choices.
