Damage in Savage Barrel

[ShaneG.]

I bought a unfired take off with similar but much worse conditions.
Almost the entire inside looked like this. I had rechambered it to 260ai and glad I never fired it. It would have been a huge waste of components. Luckily I bought a borescope before firing it.

I have a Savage Stealth Evolution in 6 Creedmoor. I discovered the first barrel had a damaged area just behind the crown. It did not shoot well so I sent in for replacement. After 2 months, I got the rifle back with a new barrel. It didn't shoot as well as a 6 Creedmoor should with good hand loads, so I looked again and this barrel had similar damage in it. This time the damage starts about 1 inch back from the crown and is about 1/2" long. I haven't seen any other damage anywhere else in the barrel. I am attaching pictures. The barrel is supposed to be button rifled so I don't have any idea how this type of damage occurs. Any ideas of what might have happened? I have used DTAC 115 gr RBT bullets and Berger 105 gr hybrid target bullets. Using H4350 with velocities around 2800 to 2860 fps. Barrel is supposed to be 1:7.5 5R rifling. The testing today with the DTAC was around 1.5 moa 10 shot groups from a rest. The best the Bergers could do was 0.8 moa groups. No signs of high pressure.

The pictures start about 1 inch from the crown then progress down the barrel to about 1.5 inches from the crown.

Thanks for your help.

Quality of pics is marginal, but to hazard a quess it could be galling from some point during manufacture. The "threads" in the barrel certainly reflect issue of quality. I think I currently own about 5 Savages and have come to the conclusion that QC at Savage is a part time position.

prolly like my QC days...if it will bolt up it's good...QC at every box builder is the same if they are flying parts in the air everything is good..when there are layoffs the cosmetics must be perfect and the inkjet pristine

Nope that is severe putting of some kind that barrel was patched multiple times.
