I seem to be having an issue with copper fouling in my M&P40. After every 200 rounds or so I seem to have copper build up in the bbl. I cleaned the shit out of the bore with hoppes #9 (which I know isn't intended to remove copper). After a very thorough cleaning of the bore I can see build up in the barrel. I took the bbl to the Shooter's Box in Malden and Steve put it in the ultrasonic. After it came out, all it took was a few passes with a brush and it was clean. I went to the range tonight and shot a few hundred rounds and now after a thorough cleaning same thing.
Steve told me to come back if it fouls up again, but I'm not gonna go there and bug him every time this happens.
I thought copper fouling was rare at pistol velocities, no?
I can't afford to go out and buy an ultrasonic set up right now. Anyone know what I can use? I hear 10% ammonia works pretty good. What's better Ammonia or the name brand copper solvents?
I mostly shoot WWB if that matters.
Thanks.
