357 ???
I've seen no mention in this thread of the fact that we are really talking about two different cartridges. Elgin Gates first developed the 357 SuperMag as a wildcat. Ruger and remington decided to go commercial with it and as all too often happens when the biggies take a wildcat commercial they have to fix what ain't broke. Thus the 357 Maximum fiasco was born.
The 357 SuperMag was intended to take heavy for caliber bullets for the steel ram. Ruger did not want to make the frame window long enough to take the 35 SuperMag, instead opting for a shorter cartridge with a light bullet at hyper velocities. Gates told them it wouldn't work. Remington loaded it with a massive charge of slow ball powder and it ate forcing cones and top straps. Meanwhile, Dan Wesson chambered for the 357 SuperMag, (Not withstanding the barrel shroud being marked 357 Maximum.) the ram shooters loaded heavy bullets and were fat dumb and happy. I've never heard of a proper 357 SuperMag load eating up barrels in a revolver.
The 357 Maximum case length is 1.605, the 357 SuperMag case length is 1.610, not much difference. The main difference is in the OAL with the SuperMag allowing heavy bullets without seating them deep in the case. A proper 357 SuperMag load will NOT chamber in a Ruger.
