I picked up a used Marlin C3030 from another forum This is my first lever action rifle and I know very little about them. There's not a whole lot about the C3030 online. All I can find out is that it's similar to a Model 336. I already did some clean up and removed the surface rust using WD40 and '00' steel wool. Bore cleaned up pretty well too with a wire brush. My concern is that with the amount of rust on the rest of the rifle, the cylinder magazine could be pretty bad too. How do I get to that to clean it? Anyone have any advice in general for lever actions as far as maintenance, things to check, etc. ? Also any recommendations for .30-30 ammo? I'm assuming it has to be a rounded bullet for use in a lever action with cylinder magazine, right?
