Dewey 27 Cal And Up Copper Eliminator Rod Due to dimensions, cleaning rods are exempt from flat rate shipping and other shipping promotions. If you are wanting a Nylon Coated Dewey Rod but are using a heavy copper eliminating solvent then the Copper Eliminator Series Rods are for you. The Copper Eliminator rods have the same extremely thick nylon coating that Dewey's other rods have but instead of a brass ferrule, they come with an aluminum ferrule. These rods are 8/32 female-ended and accept a standard 8/32 male Copper Eliminator Brushes and Copper Eliminator Jags. The Copper Eliminator Rods do not in any way remove copper easier but instead, they will allow you to not get a false positive reading when using a heavy copper eliminating solvent.
