US M1906 Multiball Cartridges

[Wineman]

The primer pockets of the the Multiball look as though the crimp was removed vs the comparison cartridge. I would have thought that if they were official, Hatcher's notebook might have mentioned them in his chapter on the 30-06 cartridge. They certainly are interesting and if an experimental load a real piece of history. Is it possible they were loaded by a National Guard or Reserve arsenal for pest control or local security?
