6.5x47 Lapua brass question

[Sray53TXTN]

I recently had a 6.5 barrel cut/rechambered to 6.5x47 Lapua. After firing I noticed some rings on my brass shoulders and my questions are:
Are they of any concern and what caused them?

Not a gunsmith, so thought I'd inquire here.

Gunny fixed it - much nicer shoulder now.

Thanks in advance!

Looks like the chamber was not polished and that the last tiny bit of chamber work was done to fast, and not cleaned enough, and it left marks..
Nothing to worry about other than it just looks bad..

Preacher,
Thanks for your reply!
Eases my concerns

What Preacher said. BUT, I would sure have doubts about using that gunsmith again. I do my own barreling and I'd be ashamed to leave a chamber looking like that. It's not so much that he didn't polish out the shoulder, rather, he did a poor job to begin with. A good sharp reamer, handled properly, will rarely leave a chamber that needs to be polished.

Mine was the first chamber cut from that exact same reamer, and they don't look like that. Maybe Mr. G.G. will show up Sunday and we can ask him what his brass looks like, also from that reamer.
