Need Help, ring on Brass - **Solved** See Pic on page 3

If there's a ring in your chamber that bad and you don't have a borescope, you will be able to feel it. Use a plastic cleaning pick with a 90 deg head.

Those heads will separate soon enough.

Hot loads don't leave rings on brass. Poorly cut chambers do.
 
***SOLVED***

So this is what we found when we removed the barrel last night. Thankfully it was a 31 inch barrel so my smith some room to work. Huge thank you to him for already getting it rechambered last night so I can start load development for a match in just over a week.

Action is Barnard model P, Barrel I was told was Bartlein. (I can't confirm that). I bought the rifle used with a claimed 200ish rounds.

Not going to bad mouth the seller "BUT" most custom target rifle owners even with limited loading experience should have caught that within 200 rounds,looks like the smith chambered it with their eyes closed, even a quick visual would have caught that.

Can't tell from the photo, how do the tenon threads look? l would have your smith give it a good once over.

My Smith did a full redo.

Glad you found the problem easily resolvable. That kind of error should have been easy to discern if you'd had an opportunity to examine a few cases that had been fired in that chamber by the prior owner. Could have saved you time & trouble, not to mention the costs associated with having your gunsmith set the barrel back enough to do a better job of chambering than whomever did the scruffy job you bought into. Let us know how it shoots once you get past your upcoming re-acquaintance!
 
how does that happen? just curious. could it have been the reamer itself or the way the chambering was done. surely the guy doing the chambering should have noticed it. never seen anything like that. tool marks in the throat sure but not in the chamber itself.

I was told something about not cleaning out small chips when chambering. I'm not 100% sure on that.

I believe it happens because the reamer grabs a chip and spins it. I believe it can happen even if the Smith clears the reamer alot. Matt

I had it happen one time. My lathe has a hand lever clutch and brake. I stop the chuck before pulling my reamer out. A chip cannot stick to a flute doing this.
