[4] In 1949, he began acquisition of powder salvaged from disassembled Oerlikon 20mm cannon cartridges. This powder resembled IMR 4350 in appearance, and with a slower burning rate, was initially marketed as "4350 Data", and later as 4831. [5]

Bulk powders were intended to offer advantages of smokeless powder for use in firearms designed for black powder. Charges of bulk powder are loaded in the same volume appropriate for black powder. Early formulations including partially nitrated cellulose with potassium nitrate or barium nitrate were more successful in shotguns than in rifles.
