White uses either solid aluminum rods or Delrin rods. Stainless steel will damage your bore, especially the crown. Always use a bore guide to prevent metal to metal contact (rod metal/barrel metal). You can also make your own bore guide using spent brass or ??... but you need one. I have one stainless rod made for me by a friend - he also included a nice nylon bore guide. Makes one heck of a loading/range rod but there is no way I would recommend one for a hunting-use rod. The Delrin rods are light, strong, durable, and QUIET in the thimbles. You would also have to work at it to get crown damage from Delrin.
