.223 fired case left with protrusion from chamber.

Has anyone ever seen this? I just shot my new savage axis .223 for the first time today. Every fired piece of brass came out with a small protusion or bump on the shoulder of the case. I shot around 50 rounds and they all look like the one pictured. It makes me think there must be a small indent or hole inside the chamber allowing the brass to flow into that void. I fired the same ammo out of another rifle to make sure it wasn’t the ammo or another cause and the other rifle did not make any marks to the brass. Any help would be appreciated.

I think you are correct on the cause. If the rifle shoots well, I'm not sure it matters. You could reach out to Savage and see what they say.

My guess is it had to be an inclusion in the barrel blank, no way I can see tooling leaving a dimple in the chamber unless it is a hammer forged barrel.

Likely a flaw in the steel forging. Unfortunately the chambering exposed it at the perfect place to make impressions into the chamber shoulder. I've saw existence of cutter loading with chips, causing rings to get grooved into chamber shoulders, but this I haven't observed before.

Thanks for the info. That does make sense I didn’t think about a flaw in the actual steel and then the reamer exposed the void. Ya I think I will reach to savage and see what they say. I really didn’t want to go with savage but there aren’t a lot of inexpensive left handed options for a .223 trainer.

Does it line up with scope mount screw holes? (I dont know this rifle at all).

My first replacement barrel had a section in the chamber where the reamer pulled some mtl and left a very slight raised area. Couldn't shoot that barrel out and change smiths fast enough.

Do you intend to load for the rifle? I don't think it's going to make any difference.
