Revolvers
Ruger once upon a time chambered the 357 maximum. I've heard rumors there was another SA, from Seville or somebody.
There is the Dan Wesson has the 357 SuperMag DA revolver. This revolver is actually chambered for the 357 SuperMag. In spite of which they mark it on the side as 357 Maximum, don't ak me why. The 357 Maximum is actually a slightly shortened version of the 357 SuperMag. So the DW will chamber the 357 mnaximum but the Ruger will not chamber the 357 SuperMag.
The 357 Maximum case length is 1.605, min OAL is 1.940, max OAL is 1.990.
The SAAMI maximum average pressure for the 357 Maximum is 40,000 psi.
The 357 SuperMag case length is 1.610, min OAL is 1.940, max OAL is 2.025.
The 357 SuperMag was developed by Elgin Gates and intended to deliver a large momentum at 200 meters using a heavy bullet of 180 grains or so, something it does very well.
The 357 Maximum was an attempt by Ruger & Remington to take the 357 SuperMag commercial, and is so often the case they had to fix what wasn’t broke. Ruger, in spite of Gates’ advice to the contrary, did not want to make the frame window long enough to accommodate the 357 SuperMag. Thus the 357 Maximum concept was born, using a much lighter bullet to achieve hyper velocities and the trouble started.
The Maximum works well enough if you avoid the temptation to drive 110 grain bullets at hyper velocities.
But all this does create an irresistable temptation for us DW shooters to snigger at the Ruger shooters. It's wrong, I know ...
