I heard about someones attempt to make a 357 magnum even more magnum. The 357 Maximum. It seemed to be a wonderful concept until they realized that, in revolvers, the super high pressures would cause the normally slight gas cutting of the top strap to go deep enough to cause significant structural failure. In under 1000 rounds.

Now today, I was thinking about this and another revolver popped into my head: the 1895 Nagant. Its known for being supressable for one reason. The cylinder moves up against the barrel during fireing. This prevents the gasses from escaping out the gap.

If a similar revolver to the Nagant, with its moving cylinder, were made chambered in 357 Max, Do you think that would solve the problem of gas cutting that doomed this cartridge to the dusty back corner of the gun shop?

Gun Gurus and experts, please chime in.

if you have shot the 1895 Nagant,you know that an old man's fart has more power than the Nagant round.probably wouldn't take much for a 357 Max Nagant round to do some serious cutting. jwr

Smith and Wesson recently solved the problem with their scandium frames; they just need to carry the mod over to other weapons as necessary. They insert a piece of spring steel in the cylinder window above the forcing cone. This insert catches the brunt of the gas and powder that escapes and erodes the top strap. Seems to me this same thing could be done for other guns. Make the insert replaceable and problem solved.
