One more for 2A

Previously, I mentioned the Puckle Gun. Now, we have the Kalthoff repeater.

The Kalthoff repeater was a type of repeatingfirearm that was designed by members of the Kalthoff family around 1630,[1] and became the first repeating firearm to be brought into military service.[2] At least nineteen gunsmiths are known to have made weapons following the Kalthoff design.[2] Some early Kalthoff guns were wheellocks,[3][4] but the rest were flintlocks.[5] The capacity varied between 5 and 30 rounds, depending on the style of the magazines.[1] A single forward and back movement of the trigger guard, which could be done in 1–2 seconds, readied the weapon for firing.[6]

So, way back in 1630, there were guns capable of up to 30 rounds!
