I picked up my .30-30 in a swap with a friend of a friend, I met while killing off a couple cold beers. When the discussion drifted to guns, he mentioned he was getting rid of his .30-30 because it wouldn't shoot. When he showed me the rifle, I could see it was not high mileage, and handed him $175, as he had scratched the receiver with a power tool removing the loading gate. He had cleaned the gun, after every season, by running a patch with Hoppes down the bore, and wiping the gun down with a silicone cloth. It took about a week of JB, and bore cleaner, and half a bag of patches.For greatest accuracy, all of us need to clean the barrel thoroughly.
