Hi Joe2,
For a revolver I'd go the 32HR mag. I had one in a T/C barrel, sold it and I" having another one made. A lot of the cowboy guys use them in the Ruger Bisley. I've watched them shoot em' and the accuracy was great. Don't forget you can shoot 32 HR Mag., 32 Long, 32 Short and 32 SW all out of the same gun. I've taken coyotes, rabbits, squirrels and the likes with this round. Several of the coyotes were at 75 yards but I would have felt comfortable out to 100 with the 10" T/C. It works great!
