Hiram Maxim originally designed the Pom-Pom in the late 1880s as an enlarged version of the Maxim machine gun.Its longer range necessitated exploding projectiles to judge range, which in turn dictated a shell weight of at least 400 grams (0.88 lb), as that was the lightest exploding shell allowed under the Saint Petersburg Declaration of 1868 and reaffirmed in the Hague Convention of 1899.
