I bought a Mosin 91/30 lin april 2011, the day I got it I put 20 rounds of wolf russian steel case corrosive ammo thorugh it and didnt clean it. ( I know bad idea). this past april (2012) I finally got aorund to dissasembling the rifle becouse i was refinishing the stock. I cleaned the barrel with windex and some break free. so what i want to know is, is the rifle safe to shoot considering i didnt clean the rifle for a year. thanks
