Hi i've cleaned the barrel of my 12ga mossberg maverick shotgun but there seems to be one small piece of something that won't come out. I've tried with a bronze brush, putting a bunch of patches on it to make it as large as possible (and still able to get through the barrel) but nothing will make that small piece (of something ?) come out. I've attached pictures of the barrel where we can see the tiny thing in there.
Also how often should you get new bronze brushes ? And is the last patch suppose to come out perfectly clean? I've got an sks and a cooey and i've never managed to get a patch to come out 100% clean no matter how any i run though it... kinda desperate.
If anyone's got any suggestions, thanks !
