….Not these! How about a 12-shot repeating flintlock?
Designed by Isaiah Jennings of New York in 1821, this rifle accepts 12 individual loads of powder and ball, each fitted with 12 individual touchholes that have 12 individual swivel covers that positions and holds the lock with each shot so that the loads are discharged evenly and in reverse order.
Sounds awfully unsafe to me. Easily broken, easily jammed, easily messed up. It’s not surprising this didn’t take off. Imagine cleaning it!
Here is a 7-shot pistol, built in the 17th century.
