The difference between the 357 Maximum and the 357 SuperMag is more than just the case length. The max OAL for the SuperMag is 0.125 inch greater, allowing the use of heavy bullets properly seated. It was meant to take heavy bullets. With the Maximum a heavy bullet must be seated overly deep, eating into powder room. The factory load with the light bullet at hyper velocity was a fiasco.

Not withstanding that it is marked 357 Maximum, the DW is actually chambered for the SuperMag, and will accomodate the 357 maximum in the same manner as a 38 Special in a 357 Magnum.

A proper 357 SuperMag round will NOT chamber in a Ruger 357 Maximum.
