yes its factory 6mm Norma BR, which was cut off-center with bad reamer marks on the body, it was very hard to cycle fired brass. I have different thread about it Hard to cycle bolt on Savage target action.

Given that the it is 'just' a partial ring, my guess would be that there is a piece of debris that is stuck to the throat and the ring is being caused when the bolt rotates to extrack the case.

Re: How would you rate this chamber job?

If the original chamber was not concentric to the bore a simple 'rechambering' will not be either unless the original chamber is removed with a small boring bar and there is enough barrel shank to set the barrel back before cutting another chamber. Few factory barrels have enough barrel shank to do this. All must be concentric to the bore. Other wise the the recut chamber will follow the old, out of line, chamber regardless . If, when putting the barrel in the lathe for the 'rechamber', the barrel was dialed in using the old chamber instead of the bore, nothing was gained as the 'new' chamber is as far from concentric to the bore as the original chamber was, maybe more. You might make "a silk purse from a sows ear" given enough material and the proper methods, but, it always costs extra!

Do sendaro barrels have enough shank for this operation?

Re: How would you rate this chamber job?

Well, my gunsmith went 0.500" into the old chamber, so that's how much I lost from the original, and I think that print on the neck is the original chamber, well now he is offering to put Brux barrel, which is a bit oversize 1.250", so I would have to give up barrel nut...

Depends upon the chambering. Jinx, if you've lost 1/2" off the chamber end, that's not the neck from the old chamber you're seeing. I'd say the new chamber is as far 'off center' as the old one.
