Thanks Lemonaid. I took a bore scope to the chamber and didn't see anything real obvious. If there is something there it's probably not obvious as the ring in the center of the case is not real deep. I'm just going to roll with it as is until I get a chance to run some rounds through it. I also bore scoped my sizing die and did not see anything significant there either and cleaned it just to rule it out. If I do figure what is causing the ring I will be sure to let you know so that you can mark your 6mm ARC that were converted from other brass as well
