This .30 M1 Incendiary Cartridge Box is a reproduction of the ammo box used during WWII. The box is empty.
These 30-.06 rounds were designed for the Springfield and M1 Garand. The M1 designation refers to the 1926 pattern shell design.
Incendiary rounds were first used during WWI and originally contained phosphorus as an explosive.
Incendiary rounds were sometimes used in place of armor-piercing shells to take down vehicles and enemy aircraft because they were more likely to ignite a fuel leak.
