I bought a brand new Browning AB3 Bolt Action .308 rifle this summer. I've shot less than 30-40 rounds through it in 5-6 trips. I clean this rifle every time it's been shot within 1 hour of finishing my range shooting. I take 30 minutes to clean the bore with hoppe's solvent and I run a regular .30 caliber brass rifle brush to break up the normal fouling. The last time I cleaned it I looked through the barrel and noticed that some (every other rifling) had some brown/orange looking substance/marks/wear on it. I attached a very clear picture of what I can see exactly.
Is this even an issue worth worrying about? Couper fouling? Is the barrel lined with something that gets worn cause it isn't a smooth clean line it's very broken up but only on the insides of the riffling I can't see it being rust as I don't notice any brown on my patches & I'd imagine rust would rub off a little bit to see.
