I just bought a new 12 ga Remington 870 Express three barrel combo, it comes with a 23" rifled cantilever, 28" vent rib and 20" turkey barrel.
I stripped the gun and cleaned it and can't understand why I can't get the barrels clean; after several sessions of soaking, scrubbing with a brush and patching I am still getting fairly dark black/brown stains on my patches. I went as far as using JB paste in the Turkey barrel with no real change.
I shot several rounds though each and re-cleaned them, the fouling cleans out like normal but I still get the stained patches especially after brushing.
Could this be a left-over from the manufacturing or coating process? I am sure it doesn't effect shooting but am curious as to what is causing this.
Thanks,
Dan
