Any of you duck hunters/steelheaders ever try shooting a shotgun out of a driftboat?! The percussion is awesome, sure makes your fishin buddies grimace!

I went on a guided trip years ago down the Hoh (don't remember the guides name) and he had ole faithful hunting black lab puppy in the back.....I thought "Cool, take your dog with ya fishing"! Anyway, we get about halfway down the float and KABLOOM!!! We never saw his shotgun go in the boat before daylight, and we both about jumped out of the boat. Turns out the guide was shooting mergansers! While probably not that legal (I don't remember if he kept it or not after his lab retrieved it), I'm sure he felt like he was doing his part on predator control!
