I tried this when I was a kid on the ranch, but I hated the taste of burnt gunpowder on my lips. Also, the moisture is bad for the chamber unless you clean it right away. The sound I got was something like a flute on steroids. I played cornet at the time, so I was accustomed to a mouthpiece, not the thin, hard steel of a 12 gauge barrel end. It was hard on the embouchure. I probably should have used a .410.
