I don't really see a practical use for it, but being cool is enough for some people. For medium/large game, I'd rather have something with more typical rifle velocities like an AR-10 in 308Win. I'm not sure what you gain to offset the loss of usable range and ability to buy ammo almost anywhere.

What advantage does it have for urban sniping? Suppressor use with subsonic ammo?

500-600gr subsonics are pretty serious. 458 SOCOM i sbasically penetration king in 223 sized platform.

Some of the more exotic bullets from specialty bullet makers make it even more interesting - Lehigh bullets, for example, make a .458 caliber 528grn VLD. Probably too long to feed from a magazine, but in a short heavy barreled bolt action with a big suppressor?

Urban sniping. That's exactly it. Subsonic and suppressed! It's getting just about the maximum terminal effect out of a subsonic, suppressed AR platform. The terminal ballistics of 300 Whisper and similar cartridges just don't compare. If a bullet has to go slow, it might as well be big. Very big. Although I would wonder how it compares to a suppressed AR in .45 ACP, in a practical sense.

I should have one of those on hand shortly for comparison (BAZ45). 230gr 850fps vs. 600gr at 850fps...I'd say 458 wins pretty decisively.
