yeah you're never gonna notice the velocity difference in favor of the casull.................unless you start shooting at very extended distances, and you're never gonna notice the difference in caliber either. it's too bad, but the big smith's just killed the .480 and i'd imagine cut into all the big bores out there b/c most just want the biggest and most powerful......and most hunters are stand hunters and the size of those revolvers just doesn't matter in that case. best use for the .500 smith imho is a huge dose of trailboss powder behind a 440 grain or larger bullet.
