I remember when this round hit the market with a lot of hoopla and fanfare in the gun mags, (as most new calibers usually do) but it's popularity with the public didn't last long. Some manufactures jumped on the bandwagon and cranked out some guns for this new round, but quickly dropped them from their catalogs. Nowadays, the ammo companies have abandoned it and no longer make factory ammo, but unprimed brass is still available from Remington. Reloading dies are also available from the major diemakers, so the round is not completely dead, but if you want to shoot it, you have to roll your own. IIRC, the two things that led to its demise were the size and weight of the revolvers made to shoot it, due to the cylinder length, were found by many to be unwieldy. But more importantly, "Flame Cutting" of the topstrap became a problem due to the pressure and velocity of gasses escaping from the cylinder gap. Smith & Wesson encountered this same problem while they were designing the "X" Frame revolver for their new hyper-velocity.460 round. They found a cure for this problem through design and materials used in the forcing cone area of their barrels. Judging by the popularity of the new "X" Frames, in both .460 and .500, and other monster guns like the BFR, I'm guessing that the public perception what's "unwieldy" has changed since the days of the .357 Maximum. Seeing as the flame cutting thing has been licked, I'm wondering if (and hoping) this will lead to a resurgence of the .357 Max in the future. I currently have one Max in my collection, but it's not a revolver, it's T/C Contender barrel. It sure would be nice to have a modern revolver in this caliber to go with it.
