Does anyone have information regarding the 327 Federal Magnum in a Ruger Blackhawk Convertible? I have one with 32-20 and 32H&R cylinders. Seems like a third cylinder for the 327 might be a nice fit. Ought to be good for coyote, pigs and such size varmints. I wrote to Ruger regarding availabliity, never received a reply. Thanks....Sky Pup
