Forcing cone issue

Looks like lead build-up. Have you tried cleaning it with a brass scraper? A used cartridge case works good.
I think it's flame cutting, Gil. Shouldn't have anything to do with the composition of the bullet. The cutting appears to be asymmetric which may indicate the barrel shank (forcing cone) and cylinder face aren't parallel and the barrel to cylinder gap may be too wide. The OP might want to have a gunsmith check it out. It may require refacing of the forcing cone and barrel setback.
No lead build up, just erosion.
Is barrel set back even possible?
It’s a pinned barrel. I will have a gunsmith take a look. I want a shooter, but the trigger is too far away for double action due to my small hands.
It was my dad’s and he had smaller hands than me. I may just get another, smaller frame revolver to shoot.

I agree and have had the same experience with 357 mag loads. I caught mine earlier than this damage and cured it by chamfering the forcing cone and reducing the powder in my reloads. I went with 800 fps.

There doesn't seem to be any flame cutting on the top strap... but if the issue is flame cutting, having a good gunsmith do a cleanup on the forcing cone (11 degrees?) might solve the problem. If it is shooting OK, I don't think the expense would be too bad. Just a thought.

No, you just noticed it! What YOU have fired in it is of no consequence. A nearly 75 year old .357 Magnum and you think that what you have shot out of it is all it has ever been fired? What is pictured is a particularly bad case of erosion That gun has been fired probably 15,000 to 25, 000 rounds in it's life, possibly even more, with likely many or most of those being full power .357 Magnum loads. Whoever, how many ever, owned that gun since 1953 shot the dog-snot out of it!
Having the barrel set back is possible, any competent gunsmith could do that. I have set back quite a few barrels but am not working anymore. The pinned barrel isn't an issue, the notch for the pin in the barrel merely needs to be widened slightly. But, WHY? if the gun doesn't fit you then sell it to someone who would appreciate it for what it is and buy a K-Frame revolver. The gun is a "shooter" as is, nothing needs to be done to it
Buddy, that’s what I’ve been thinking.
I don’t load past 1050fps anyway.
I have hit 1100fps with 2400 but I’m almost out and won’t be buying anymore anytime soon.
I doubt that the erosion came from 2400 and lead bullets. I would guess a lot of 125 grain or less at maximum load H110 or other ball powder. Whatever, I would have to have it fixed!
There IS flame cutting on the underside of the top strap. Not much but it’s there
Gee, that barrel looks a lot like a couple of my guns!
I would guess the OP has never owned a mod 53! The pics are of barrel erosion, which is common with the mod 53, 22 Remington Jet! The cause of this is too much hot powder and there are those that would include powder in the form of balls, not flake and/or cylindrical shaped powder granules causing a sand blasting effect from the unburnt powder escaping thru the barrel to cylinder gap.
