The RCBS Case Lube kit is an ideal for reloaders looking to have all of the necessary equipment to properly lube cases. RCBS Case Lube-2 is a water soluble non-toxic lube that leaves behind no sticky residue. Simply squeeze a little on to the included pad and gently roll the cases over the pad to achieve an even coat. Then use the included brushes to put a little lube into the case necks.
