SPECIFICATION for loading shot cartridges, Carbine, Caliber 30 ML* 
The standard Carbine, Caliber 30 Ml, :rimed shell cases are used. They are 
loaded with .356 gram of Kleanbore Shurshot Powder (Dupont)* as loaded in Remington 
Shotgun Shells* The powder is compacted sufficiently behind one hard cardboard wad 
.030 inch thick, to leave room in the case for approximately 4*6 grams (70 t) of #8 
chilled shot* The case is crimped over a cardboard front wad of *017 inch thickness 
This should be waterproofed by a plastic varnish or porafin coat. 
• It is most important that this particular powder be used; no other tested app¬ 
roaches by 20$5 the consistency of shot patterns that this type produces, without 
malformation of the shot in spite of the absence of all packing or cushion wads.
