Hi, I'm new to this forum, and have a question, I cleaned my .308 about a month ago, used copper cleaner and got it really clean, after I finished I checked the bore for any grit that may have been left over, there wasn't any, but when I got my .308 out today and checked it over for the upcoming deer season, I noticed a couple of particles or something about midway down the bore, I didn't think it was possible because I saw nothing in the bore when I put it up, whatcould these particles be? , should I be worried? Thanks.
