Reloading a bunch of pistol brass got my ram all dirty, and my press started making some crazy noises too. I used a few squirts of TriFlow. It is a lubricant used mostly for bicycle chains, but also for fishing reels and other stuff along those lines. Once I put some on, I worked the press a bit, then wiped the ram as clean as I could get it, and then reapplied the oil lightly. Now it is smooth as can be.
