A guy was walking out of NGD in Louisville at the December show. The instant I saw the bore, I realized it was a Quarter Pounder. He wanted big bucks for it (and I wasn't in a buying mood.)
The other time I saw one in Louisville, about 15 years ago...I bought it!
It now resides out in my garage, blocked in by one of my jeeps. IT came with a bunch of stuff, not the least of which being a few pounds of 1" round balls. And better still, a bullet mold. The problem is, it doesn't have a stock, its got a carriage. Its a cannon.

And the barrel isn't all that long, maybe 15" or so. I haven't looked at it in a few years now, except to accidently kick it with my foot (the now sore one.)
My wife won't let me shoot it, something about the authorities having a poor sense of humor. I'm pretty sure I could shell the Yankees over in Ohio. I have no idea what the range would be, but I feel pretty sure Paul Brown Stadium is in range!
There's even a name plate on the thing, it was made in Arrid-Zone-a. I tried repeatedly to contact the company but never could. All I wanted was to learn about the thing.
