If a man I once knew could have shown the inventor how fast he could shoot/reload/shoot a single barrel 12 ga. that thing would never have been built. We drove deer with dogs in the swamps when I was a young man and there was an old guy who only wore bib overalls (not camo) and shot a single shot. He held two or three loads of buckshot between the fingers of his left hand when he shot at deer. He could eject an empty, reload and shoot again faster than you could imagine. When hearing the reports lots of people thought he was shooting a pump.
