454 500 460
As for hunting, Mr Casull did a damn good job. For deer, hogs, elk, black bears, this gun is great. If you want to hunt larger game like moose and brown bear, make sure you have harder lead, and great shot placement. As for the RB 500, its a good gun, and will handle the load fine, but there is one little hickup. The cylinder in the RB is just long enough for factory 500 loads, that means that some hand loaders who like longer lead, can't fit it. But if you arent interested in some huge chunk-o-lead, no worries. I have to tell people looking at the 500, to look at the 460 Sw magnum, brand new cartridge, but only Sw makes the pistol. Same energy as the 500, but way faster 2300ft/sec, and also a rediculously flat trajectory. I recommend everybody who is looking for a massive pistol to check this thing out. It also shoots the 454 and 45LC.
