If you want to see a manchild (and I say that in the best way possible) do fun stuff with a punt gun, I recommend Kentucky Ballistics on YouTube.

I fired a punt gun once (side-by-side double 4-gauge). It was quite an event.

Huh. I was just talking about these with some coworkers yesterday. None of them had ever heard of them, and here I thought gun nuts would have more knowledge about the history of firearms.
