Visit Lewis and Clark National Historical Park and discover one of the most fascinating pieces of technology carried by the Corps of Discovery: the Girandoni air rifle. Unlike anything many people had seen before, this repeating air rifle could fire up to 30 shots on a single charge, which was an incredible feat for the early 1800s. As the Corps traveled west, demonstrations of the rifle amazed the many communities they encountered. Invented by Bartolomeo Girandoni and later used by the Austrian Army, the rifle operated without gunpowder. Instead, air was pumped by hand into a reservoir attached to the weapon. Preparing the rifle required serious effort—about 1,500 strokes of a hand pump to fill its air reservoir. Today, only a small number of Girandoni rifles remain, and one is on display at the Fort Clatsop visitor center museum. Stop by and see this remarkable piece of history that was part of the Corps of Discovery.
