Gents,
Im building a 6mm ARC AR15. And I am really excited about the prospects of having it all finished and running smoothly. I was at the range today shooting the first few rounds throo the barrel to break it in before sending it off for nitriding. But ... after sending a round down range the empty case sticks n the chamber. with a bit of extra force I can extract the casing. This happened 12 out of 12 times. On examination of the casings all of them seem to have two “scratches” on the neck parallel to the long axis of the case. Any input would be appreciated.
