I don't have one, but here's some info..

Guns designed for the .357 Maximum were built on a larger frame than their predecessors. Although Ruger only made 7700 Blackhawks chambered in .357 Maximum, the frame size has been used as a base-gun to build bigger revolvers in .445 SuperMag and both the .475 and .500 Linebaugh Long/Maximum.[5]
