Soaking Ram Rod
A ram rod can be soaked in Kerosene or Lamp Oil to improve its flexibility and reduce the possibility it will break.
Remember to buy 2 or 3 of them to account for breakage or other damage over the years. Nothing worse than not being able to shoot due to no ram rod. Having a "range rod" to use when at the range and home cleaning is a good idea to. The vendors mentioned will set-up up with a range rod complete with muzzle protector.
