20 h 27 m, 20 maio 1863 ano - Spenser

Descrição:

Introduced at the start of the Civil War, Spencer repeating guns were technically advanced, used cartridges (a recent development), and could fire 7 shots in 15 seconds. But the Army didn’t want a repeating gun, fearing that soldiers would fire more often, constantly need fresh ammunition, and overtax the supply system. But in 1863, President Lincoln test-fired a Spencer. His approval led to the purchase of 107,372 Spencer repeating carbines and rifles (of 144,500 made), and the Spencer became the principal repeating gun of the Civil War.
