Another comment on BP for defensive use. My father in law has been having problems with coyotes messing with his animals on the farm. Recently, he was out with the sheep whilst packing one of my '58s with the Taylor's conversion. Now, it's no longer a "cap & ball" revolver with that on there, but the spirit is intact.
Anyway, there was a 'yote lurking aboust that ended up on the recieving end of a 230 grain slug from the '58, which ended the dog's day pretty quick.
