Pits are stress risers/concentrators

For us non-deep (pun intended) thinkers, scroll down about 1/2 way for pit-like illustrations.

However, the MWT at the bottom of the pit does not necessarily determine bursting pressure.

As said, Birmingham Proof House requires removal of pits prior to re-proof
http://www.gunproof.com/Proofing/proofing.html
Proof regulations require that shotgun barrels shall be �struck-up� and smooth and that insides shall be clean. Pitting should be removed so far as is practicable, bulges knocked down and dents raised.

Drew,
Thank you for that.
I figured there'd be FEM analysis out there on such defects....sorry "stress raisers"

My first pick would be Allem since they have been doing barrel work for a couple decades that I know of and I believe they have a fluid hone. They will also talk with you on the phone and are very prompt with their services.

Slightly OT, but this stuff is supposed to stop rust. It's what the Army has switched to in order to protect artillery tubes. Not merely the liquid, but the Army uses the tube inserts as well. I use it.
