Ring necked cases

While troubleshooting a problem on an older rifle, I noticed the fired cases have a "Ring" around the neck of the case. What can cause this? Its apparently been doing this for two years and hundreds of rounds. It wasn't until I got another rifle of this type that I noticed it was doing this to the cases.

I have a similar rifle that does not do this. Same make, different year.

I could be wrong, but to me it seems like there is a deformation in the chamber of your rifle. Does it only have the ring after firing or is it noticeable (even if not fully developed) on an unfired round?

It almost looks like you had a case separation just ahead of the shoulder, and there is still a thin layer of brass still in the chamber. Time to get the brightest light you own and spend some time staring through the barrel.
