I'll vote Raging Bull in .454. Mine wears a 6" bbl but they can be had in shorter versions AND in 44 mag if you prefer. I like the big heavies but you can also load hot 45 Colts as mentioned before. These guns are well built and accurate. I know you are concerned about bad breath distance but the .454 shoots pretty flat too. It carries as much energy at 100 yards as the 44 does at the muzzle. It ultimately depends on your "want" and your budget.
