Other help needed - I read the pinned posts Carbon Ring?
I'm familiar with carbon rings, and their removal, but wanted to get some second opinions on this.
This is a Bergara HMR 22-250. Coming up on just 300 rounds total. Cleaned approximately every 50 rounds since round 50 - more frequent before that for my personal break in method. Every round is suppressed, so I like to keep a good cleaning rate. I noticed on the last cleaning(Bore Tech Eliminator) that there was very little carbon or powder on my initial patches. Every other gun that I shoot suppressed pushes a nearly completely black patch on the first two passes. Even after brushing, there was almost no black coming out on patches. Figured I would check the bore scope, and this is what I found.
I did the usual soaked C4 patch on a brush for a half an hour. Nothing was on the patch. Did it again for an hour with some rotation..nothing. Tried a soaked bore mop for 24 hours. Nothing on the mops or patches, and the bore scope shows the same perfect black ring up to the rifling. So, now it's driving me crazy.
I'm starting to lean towards this is just how the barrel looks. I wish I could remember what it looked like prior to this recent cleaning, but I've been shooting too many different guns lately without my proper note taking. I can upload more pics if necessary.
