Thanks to a friendly collector, we had the chance to take out one of the new, gorgeous reproduction 1877 Gatling guns being sold by Colt. It's a near-exact replica, with the added feature of being able to crank backwards to safely clear any loaded cartridges out of the action. Being a Bulldog model, it has 5 short barrels (18.25") chambered for .45-70, enclosed in a full brass jacket to keep the action clean. Colt claims it will do 800 rounds/minute, but we got it going a bit faster...

Thanks to an interesting quirk of US gun laws, the Gatling is not considered a machine gun - so anyone who can possess a bolt action rifle can own and shoot one of these. The crank handle is considered a trigger, and each partial turn fires a single round. Since a single discrete motion doesn't fire multiple rounds, it's not subject to the registration and transfer tax of a machine gun under the NFA.
