First - all guns are always loaded. Bouncing a ramrod off the breech face doesn't prove it's unloaded - it just means the gun can leave the line pointed in a safe direction and be secured in it's case. Yes, I know the rod will react differently to loaded and unloaded conditions. The point is the first sentence in this paragraph.
Second - ramrods are not all the same. A light hickory rod will react differently to bouncing than a heavy solid brass rod. The key is to get to know what YOUR rod will do in a specific situation (seated, short, AND empty) in YOUR gun. IMHO, one really should know that.
