Do you have a pic of the brass that shows it. I would be calling the manufacture about it if you haven't already and get them to fix it.
One of the 2 I have seen was an old Ithica M1 Carbine deluxe in 256 Win Mag that not only had machining marks in it but would lock up when shot. The brass had rings around on it when tapped out with a cleaning rod. 256 is a 357 Mag case necked down to .257
The other was a custom Savage Barrel in 7 Nosler before it was SAAMI. He was showing pressure signs with starting load powder charge for the 26 Nosler, the smith fixed it (he had forgotten to polish the chamber).
