I'm a big proponent of conserving calibers, so since you already own a .357 mag revolver I would go for a lever action rifle chambered in .357.
Can't go wrong with a Marlin 1894c, Win 94, or a Rossi 92.
You know nothing. In fact, you know less than nothing. If you knew that you knew nothing, then that would be something, but you don't. - Ben Harp
