Given you're a bow hunter I think a 357 would be fine if you hunt just like you had your bow. If you want to be able to reach out a little farther without going all the way to a 44 then a 41 Magnum would be a good round to start with. S&W makes the model 57 classic or you could go with a Ruger single action. There are occasionally hunter models out there too.
