The packing tool set consists of two drilled aluminum casting bases with matching 3/4" or 1" diameter 14" long teflon mandrels, a wooden handled polypropylene ram, and a mandrel extraction wrench. This makes packing a much faster and easier process than using the packing tool included with the class. It also eliminates 95% of the propellant that is normally drilled out and wasted.
