Good or no good ?

[tatou]

I've taken classes in acetylene welding and brazing, and it looks as though the action was held with a vise tightened on the action barrel ring, so that would have acted as a heat sink. There's a good chance that some of the brazing material may have entered the receiver ring and also secured the barrel. Has the extractor been removed? If not, it will act like a "key" in the breech face to lock in the barrel. The only way to tell the condition of the barrel for sure, is to remove the barrel and look for signs of heat damage. Sorry, that's my best advise. Hopefully, someone with more experience can provide better or more information.

Hey any advices is good advices. I appreciate any help.
There is no visible sign of brass, on the top (outside)) of the bolt... i was/am hoping no brass (or very little) got to the barrel.
Yes the extractor is still in place, it is visible through the semi circle notch.
I think i can get at it with a small Dremel wheel cuter.... heck i'm even willing to cut the bolt head and a portion of the receiver ring, to free up the barrel if there are any chances to save the barrel.

Would i be right in assuming the scaling we see on the receiver is a result of intense heat ?
Haven't tried to scrape it off or anything ... yet.
There is a little of that scaling on the chamber portion of the barrel, but not too much... way less than on the receiver.
Almost look like the bluing got burnt off ... it's weird.

Oh... btw the eat was high enough to ruin the bolt spring and the rear sight spring (if that is of any help)
Well they remain a little ''springy'' ... but not much...

I know, no one can judge if that barrel is good or not by just looking at pictures.
Just trying to see if it's worth to even send it to a gunsmith (for inspection or what ever) and have it mated with the good receiver i have.
This is just out of my knowledge basis.

The heat caused by brazing would definitely leave scaling. If you had access to a bore scope, you could check the chamber and throat for indications of scaling. One of my books states that you can use an acetylene torch as long as you keep the temperature to the point that the colour of the bluing outside the contact point is not affected (the topic was annealing two (2) points on the top of a Mauser 98 receiver ring (notorious for being heat treated extremely hard on the surface, but dead soft internally) so that it could be drilled for tapping, and also involved using heat sinks. The writer stated that you shouldn't be able to cut the Mauser receiver ring with a file if it was properly heat treated). Under the circumstances you describe, unless the barrel has extremely valuable assets (pristine bore, special markings, rarity), or you're just suffering from Covid madness and want something to occupy yourself, salvaging the barrel is probably a lost cause.

After reading many of your posts, I believe that half of your motivation is the challenge. Personally, I've never removed the barrel from anything that wasn't a "take-down" model, although I've read the mechanics and methods involved. It could prove to be a learning experience, even if the barrel can't be salvaged.
