The packing tool set consists of two drilled aluminum casting bases with matching 1/2", 3/4", or 1" diameter 14" long teflon mandrels, an aluminum handled polypropelene 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.
