The military team in the Ottawa pistol league would trade a brick of their D.N.D. issue for a box of Super Clean.
Their ammo gave them lots of opportunity practicing to clear jams and FTF.
With the Super Clean they could compete. In a time line, Super Clean came between Canuck and the Dominion (100 per box).
Super Clean and Whiz Bang were produced at the same time in the 50's, 60's and 70's, IIRC.
