U.S. Colt Model 1890 Gatling Gun last purchased by army RIA
The M1893 Gatling, the first chambered in .30-40 Krag. This wonder, fitted with 10 31-inch octagon barrels, could let those big buffalo-killer sized rounds rip at 525 rounds per minute, which would produce a giant billow of burnt black powder in the process. Weighing in at 200-pounds (sans bipod) this thing was a beast to run but had all the bells and whistles of a modern Gatling design including the Murphy Stop and the Bruce Feed.
