A snubby in that caliber is not that bad, believe it or not. With those big bullets, you don't need alot of fps behind it because they are still moving at a good speed.
I haven't fired a .480 Ruger yet, but I do know from reports of those who have that they were totally surprized by its soft recoil. A full load of .480 Ruger (.475 Dia) recoils less than .454 Casull (.452 dia) and a whole bunch less than the .460 S&W Magnum.
The .480 Ruger is also nic named the .475 Short since it is not as powerful as its big brother the .475 Linebaugh cartridge.

Subjectively, I agree. After firing a trio of identical-length Super Redhawks with Hornady’s own 300-grain .44 Magnum, 325-grain .480 Ruger, and 300-grain .454 Casull loads, I’ll testify that the .480 feels much more like the .44 than the .454, and I can shoot the .480 for as long as I want without undue stress. Eighty percent of the .454 Casull’s power with half the recoil—no wonder Hornady believes the new .480 Ruger “takes handgun performance to an entirely new level.”
I think I am pretty much interested in this cartridge....
