Paper Bullet Round per WWI "FA 8 07" handstamp.

A "Blank" Cartridge for the Model 1903 Springfield Rifle.  Identified by their longer cases, these paper “bullet” blank cartridges were issued to the soldiers for marksmanship practice sessions, ceremonies and during training sessions to accustom the horses of the Cavalry and Artillery to gun fire.  The rounds retain the original tin plating, which distinguished them from the regular ball service rounds in brass cases. The round is loaded with a paper bullet and is headstamped “F A” for Frankford Arsenal, August 1907.
