FOLDED, U-SHAPED OR ENCAPSULATED AMMUNITION WAS ONE OF THE MOST INTERESTING EXPERIMENTAL PROGRAMS CONDUCTED DURING THE 1960s and 70s AT FRANKFORD ARSENAL.
Invented by Andrew Grandy (seen below in this FA publicity photo) the concept provided a separate combustion chamber. This allowed gases only to be conveyed to the base of the projectile instead of the unburned powder and gases which are typical of the traditional "in line" cartridge design.
The concept was tried in several calibers.
Production and chambering problems for a nonsymmetrical case undermined the development.
Mr. Grandy was a long time ICCA member. The ICCA - International Cartridge Collectors association was the prior name for the current IAA - International Ammunition Association. In 1984 he produced commemorative sets of his folded ammunition design for the ICCA.
Frankford Arsenal produced a bicentennial commemorative dummy of the folded ammunition with FA 1976 headstamp. These were solid plastic case with raised headstamp. They are loaded with micro-hollowpoint projectiles.
This is the blue one.
Includes a descriptive flyer which explains the concept.
