Seriously...I always use the same cleaning procedure. I do it every time I clean my barrel which is after every time I shoot. If I've shot several hundred that day I run it through the bore bare before using solvent-soaked swabs. Otherwise I wrap a thin patch around a bore brush (so the bristles poke through the patch) and run them both through wet.
<blockquote><I>"unknown---How do you clean the plastic buildup without cleaaning the bore.Am I missing something?"</I></blockquote>It must be me who's missing something. What did I write that gave you the impression that I said what you think I said??
