Copper fouling or not?
O.K., so I finally received my cleaning supplies in and got around to cleaning my .270 of the crud that's in the barrel. Unfortunately I only had one old bronze brush that has been crushed in the bottom of my shooting box, so I really couldn't do any scrubbing at all - I'll pick up some more tomorrow. Anyway, after running about 10 or so patches down the barrel (soaked with 2/3 Shooter's Choice 1/3 Kroil), and letting it sit a couple of minutes between each one, I can still see quite a bit of copper streaks at the muzzle.
Is this what is considered copper fouling? If it is, do I need to get something more aggressive to get it out or will a new brush likely scrub it out? (The one I used was pitiful)
I can't believe I let my barrel get dirty anyway as I'm usually a stickler about keeping my weapons clean. [img]/ubbthreads/images/graemlins/blush.gif[/img]
