Pomeroy bullet

Pomeroy bullets were supposed to explode when encountering the minimal resistance of fabric envelopes containing hydrogen gas holding the zeppelin aloft.

At the age of twelve, a hardware store paid him £50 for the design of a support to hold clothes lines above the ground without tipping to one side.

His proposal for dealing with zeppelin bombers was adopted in 1916 as the Cartridge S.A. Ball .303 inch Pomeroy Mark I.

It was a standard .303 British cartridge loaded with a 155-grain (10.0 g) cupronickel-jacketed lead bullet including a hollow copper tube filled with 15 grains (0.97 g) of 73% dynamite.

After Brock was killed during the Zeebrugge Raid, Pomeroy promoted his design while receiving £25,000 for production of these bullets through World War I and entertained his customers with stories while selling pies from a horse-drawn cart in Melbourne through World War II.
