When my eyes started to go I switched from NRA High Power to Skeet
200 rounds with that cylinder certainly provides a data point, but you'll need to see how it does after a few thousand rounds for more data. In fact, I would do examinations of the weapon after every 500 rounds to look for changes indicating wear from the centerfire ammo.

With that being said, though, 21,000 PSI isn't really a high pressure. 38,000 and higher is where your Magnum calibers run, and plenty of top strap designs have proven themselves able to stand up to thousands of high-pressure rounds.
I really would be interested to see how many rounds your setup will run before you need to do work on the arbor or another part subject to pressure. It would be a good experiment to run and lots of fun.
I'll volunteer if you need someone to help you with the shooting, too. I wouldn't want you to wear out your hands with all of that reloading and shooting. I'm more than happy to help contribute to your scientific research efforts.
Hey Mike, in response to the @TrapperDude I’m interested in your opinion. Trapper said, “Even the barrel, where it mounts into that lug, is supported only from the bottom. That's a lot of force being generated all from one side, which as pressures increase, would make for some interesting long-term effects, not to mention accuracy with those higher pressures.”
And that’s what I was referring to. Place it side by side with an SAA of Blackpowder vintage. You’ll notice that the strength of the revolver is derived from the use of modern materials and not by supersizing the frame, cylinder or barrel.
The Chief has never had any issues with our spending habits. For toys or anything else. We do have discretionary limits under which no discussion is required. She also has a very good idea of the values of everything so when I croak she’s prepared when my “friends “ come snooping around…Well not saying be shifty about but it reaches a point the bride simply doesn’t know. Then again we have reached a point in life that income exceeds what’s owed.
Yeah, tongue in cheek. I doubt anyone has the inclination to go down that road. Maybe if I was 30 years younger?
As a rule, I’m the opposite. Still, handguns are best used to fight your way to your rifle, your friends, and their rifles.
I actually want to see a modern centerfire chambering of .357 Magnum or larger used to test that.
Well, the barrel is supported by being pulled onto the arbor ( why the arbor length is important) with great tension. The barrel lug is " located" on the frame by two pins and yes, is in a compression during firing. That makes it a foundational structure (constant) and is why the arbor length is the determining factor of "endshake". The force at firing being above the arbor is why the compression structure is just that. I agree that there is no problem and the barrel lug footprint is substantial!
they are notorious for being easy to break
It seems that the wedge and barrel slot would have to pretty huge to prevent deformation with the use of higher pressure loads. Even with absolutely precise fitting to prevent less than perfect contact between the wedge and the rear of the slot, that force would have to be distributed over a larger area to prevent eventual slot stretching under the force of really high pressure levels. Otherwise, the arbor and barrel slots, themselves, would stretch, even if the wedge didn't deform.
First buck and ball round from lower barrel might be all you need.
