What happened to the 357 Maximum erosion issue?

Since the Ruger 357 Maximum erosion fiasco we've had several supermag chamberings, the latest being the S&W X frame 350 Legend. What happened to the erosion issue? You could make an argument that the 350 Legend amounts to a rimless 357 Maximum, although if anything a bit longer and hotter.
 
I agree the problem was mostly due to trying to make it do something it was never meant to do, hyper velocity with the above type of load. But I figured the scare would last longer.
Ruger has yet to bring back the Blackhawk Maximum. Not a peep about it with the new S&W, not even a mention that it was due to improper loads. The 350 Legend factory load is meant for a rifle. Not ideal for a revolver. Always seemed to a replaceable stainless shim under the top strap would solve the problem.

BTY: The current Rifleman article says it's the first rimless revolver chambering from S&W. There are SW revolvers chambered for 45 ACP, 9 mm. 10 mm, and 38 Super. The later quite rare.
 
Seems like the major players have moved on. You can probably still get custom T/C single shot barrels in 357 Max from several niche companies, but it seems like both the Encore and Contender are in production limbo right now.

FWIW, I have an H&R Handirfile barrel that reamed out for .357 Maximum and about 200 rounds of handloads. Haven't shot it that much -- finished the project and got distracted.
 
Even Starline said the .357 Max was obsolete until some states relaxed cartridge rifle hunting rules. :(

The only .357 Max that I have ever seen in person was a Dan Wesson .357 SuperMag with the 8” slotted IHMSA shroud, it was locked in the evidence locker at the PD I used to work for. The gun was awesome, but it was surrendered or seized or whatever, so it was forever gone. The dozens and dozens of piece of crap Lorcins, Ravens, Jennings and other beat up crime guns were one thing. I almost stroked out when I learned I was escorting a van filled with the DW, a sweet Wildey .45 Win Mag, a Belgian Hi Power, a Weatherby Athena and a bunch of other really nice guns in there to the Tamco steel plant to be made into rebar. (It was a sad day for nice guns indeed. :thumbdown:)

Stay safe.

This has nothing to do with the question asked by the OP.

I just wanted to relate a similar story.

Many years ago I worked for my small towns street department.

We were tasked with many odd jobs that I never expected.

One job that I assisted in my 14 years there was destroying evidence.

Couple times a year the Chief would bring down a couple cases of beer that they had confiscated from underage kids and, with a wink, would say "here, destroy, this over the weekend"

One day he brought down his cruser with the trunk half full of firearms; many suicide, a couple of crimes and a lot of one's that widows who didn't know what else to do with the just brought to PD.

Many of these guns had been sitting in the evidence locker for decades after already serving their purpose in the courts.

A coworker and I were tasked with torch cutting these firearms, with full supervision of course.

I remember a lot of Locrin, and HI-Points, Taurus but also an old S&W .38spl and a Winchester or 2.

The most heartbreaking was an old Luger, it was a suicide gun.

I asked the Chief if he would just turn his head for 10 seconds but that wasn't going to happen.

Well, it’s been almost 40 years, so…

The Maximum Blackhawks were a Reloaders Revolver, and Ruger doesn’t condone reloading, plus, Silhouette isn’t a popular game any more, and building specialty products for a declining niche isn’t really within Ruger’s marketing strategy.

Why is the Legend revolver available? Well, as an attempt to convert the new demography of gun buyers to take a look at a revolver. It’s co-product marketing, a modern twist on the mythos of carrying a rifle and a sidearm chambered for the same cartridge, without being hamstrung by the extremely limited potential of pistol cartridge carbines which match conventional modern sidearms. S&W already has a stretch limo chassis, so they have ridiculously low capital investment to retool to make Legend revolvers, hence their major expense in the launch is really just marketing overhead.

Compounding Ruger’s limitation, naturally, is the fact their stretch limo was ~.4” shorter cylinder and a hell of a lot less hefty than the S&W X-Frame, and of course, a single action rather than a double action… So Ruger relaunching the Maximum Blackhawk would be welcomed by jeers of “check out Ruger’s new extra-lar…Schmedium…biggerish stickshift model…” how well does anyone expect that to sell in the case beside a more powerful double action? Hell, look at their own model line offerings - it took YEARS, what, almost 2 decades, for us to get 454c & 480 Super Blacks, which took hardly any retooling at all, and which custom builders had been doing for a long, long time as proof of concept… But in the 20th anniversary of the X-Frame, the revolver which effectively dethroned Ruger as the producer of the most powerful factory revolver on the market, Ruger still hasn’t chased that particular rabbit to reclaim the supermagnum market… why? Because their strategy is to make “apparently specialized models which have exceptionally broad market opportunity.” Supermagnums don’t. So whether it’s a Max-Hawk reboot or an X-Frame competitor, we’re just not get seeing a stretch frame from Ruger, and I don’t think the 350L X-frame has the draw to change that.
 
357 Maximum is a neat cartridge, but very very niched market even when it was in its prime in the 1980s.
It reminds me of similar performance to a .30-30 winchester and would be a great Carbine levergun round out of a Model 94 "Trapper" Carbine, IMO.
 
From what I read the main issue with the flame cutting related to the timing of the pressure curve, the bullet jump, and the forcing cone gap.
Certain ball powders (H110) when loaded hot under certain weight bullets 125 grains and under.
The light weight of the bullet allowed it to be accelerated through the chamber/barrel gap before the powder has fully combusted so that high pressure hot gas combined with unburned ball powder particles acted as a sandblaster to the forcing cone and the top strap.

Heavier bullets took longer to start moving which allowed the powder to burn more completely by the time the bullet was through the chamber/barrel gap so the sandblasting action was mitigated.

It was all just a circumstantial timing issue of several factors coming together and not an inevitability due to cartridge size

Great explanation of the phenomena here ^^^
 
Some people think “Ruger Only” loads apply to every handgun they make!
 
The .357 Maximum erosion issue was caused by those using the wrong powders and wrong bullets. The Ruger SRM, Dan Wesson SuperMag and United Sporting Arm's Seville were never intended to be varmint revolvers. They were meant to slam steel at up to 200 yards with enough force to topple them. They also turned out to excellent medium game weapons. Lightweight, fragile bullets are ill suited for both of these applications. Rugers had the added issue of using a shorter cylinder.
Still, some gun writers thought they knew better. You know, like our recent Covid experts.
 
Can 357 Max brass be shot out of the new 350 Legend S&W revolver?
The diameter above the rim of the Legend is .390". The diameter above the rim of the Maximum is .379". At the pressures these cartridges create, I wouldn't try it.
