I have a personal preference for the Ruger Super Blackhawk; it treats me well anywhere from the 44 special to 300 grain magnum loads. The curved grip of the single action serves as a built in recoil reducer. I put a trigger kit in mine and it is a keeper. I haven't tried a Bisley model but check them to see how they feel. 357 is already legal for deer in some states. I'm wondering how your terrier handles the noise?
