RE: Hunting pistols
.41Mag. or .44Mag. - either one will do the job for you. I'm partial to the .41Mag. myself. If you handload, take a look at the .45 Colt. It can be loaded up pretty stout,
and will handle about anything you like. Of course, you'll need to limit your choice of
gun to something like the Ruger Blackhawk which can take the hotter loads for the .45.
There are other handguns that can handle it, and these are noted in the reloading manuals. Then too, there's always the Cor-Bon ammo for .45Colt. It'll do.
