[QUOTE="Jake in NC, post: 27266, member: 878"] Hey guys.. Thanks for the input.. They aren't land marks.. I spent a good deal of time getting the seating deapth correct for these bullets.. (4.380 comparator OAL, if I remember) I talked to Mr Romaine and he says these chambers are throated very tight.. We borescoped the chamber tonight and all looks new except for a little ring of copper right where the tight freebore starts.. I can't say that I've ever had to deal with this issue before.. Could be I've just never noticed it with looser tolerances.. Who knows.. What's the scoop for getting rid of this thing.? Is this what's referred to as a "carbon ring".? ..Also.. .. The bore is completely black.. I usually shoot with moly but didn't with this project.. I don't think DC used it either and I don't remember if I asked CJ about it or not.. I wonder what that could be.. I'm somewhat certain I'm cleaning OK.. Or maybe I've been "moly-spoilt".. d:^) JiNC [/QUOTE]
