Chamber dent?

[IrishLaw]

Today after shooting, I was cleaning my garand when I noticed an odd deformity on the inside of the chamber where, I believe, the bolt is/was hitting it. I have attached a close up of the mark in question. Is this something that is known to happen or is it something I should be concerned about? The rifle functioned flawlessly today - loading, shooting, cycling, ejecting, etc.

(ignore the small white cat hair that made it onto the chamber just above the area in question, haha)

Thanks!

Looks like old dent, its not shiney right? Rifle has been refinished and it looks like dent is under the finish. Anyway have seen it before, I wouldnt worry about it

Normal bolt to receiver breakin damage. Probably caused by the original bolt. You're fortunate, I've seen and I own a couple with much worse. Nothing to be concerned with.
