[QUOTE="fta0303, post: 3082571, member: 43503"] It seems that you are getting carbon build-up on the case neck after firing, since you are having to clean with a 3M pad. This shouldn't be happening. It indicates that the neck portion of the chamber is cut a bit too big. I had a 6.5-284 built, and it came with this problem. If I recall correctly, I confirmed the problem by measuring the neck diameter on a fired case - it was larger than spec. I asked him to re-cut the chamber to 6.5 Wby RPM, he did, and that problem went away. I see your photo of a case standing on end, with a ring of metal around the neck. It looks like this case is a fired case. I'm thinking that you resized it and got this result (?) If you try to use a properly made resizing die on a fired case that has expanded in diameter beyond spec, it might build up a shaving roll something like pictured. Just speculation, though. [/QUOTE]
