@Doomguy666: it's best to clean a rifle after every use. Store the rifle in a low humid spot. Get dehumidifier packs if needed (or a safe) and it should be ok. Safes are pricey, but if you have just the one rifle, then it should be fine in a case.
@vex714: once I get the initial fouling clean it should be good as air doesn't have the same velocity as gun powder. It's just really bad from the factory.
I'm using a bronze brush and solvent, it just won't get clean.
@vex714: it's the same rifle I mentioned last time and it's notorious for having an extremely foul barrel from the factory.
My my m&p shield doesn't get this dirty and I practice with it every week.
