Reuben Harwood

Reuben Harwood (also known as Iron Ramrod ) was an American gunwriter and cartridge designer from Somerville, Massachusetts, at the end of the 1800s.

Among his notable developments was the .22 Harwood Hornet, a predecessor of the modern .22 Hornet cartridge. Harwood's cartridge, unlike the modern Hornet, was formed by necking down .25-20 Winchester brass to .22 caliber, and was initially loaded with black powder. Further innovations of his included work on an auxiliary chamber, and experiments with .25 caliber rifle cartridges.
