Shooting fish in water? Why?
Well, here in Tennessee it's illegal to lasso fish. (Yep, there's actually a law that says so.) I don't know about shootin' 'em.
Once had a gar get himself all wrapped around my line about three feet from the hook. It looked like he had been roped somehow. Glad nobody outside the boat saw it. I'd a hated to have been arrested for lassoing a worthless gar. My partner freaked out and beat it to death with a paddle. He'd a shot it if he'd had a gun. Good thing it was his boat. Wouldn't want any bullet holes in my boat. He must've had a bad experience with a gar when he was a young buck. Never saw a growed man go bonkers over a fish like that before.
I did shoot a snake in the water once with a .38 using CCI shot shells. Shot him twice at about 6 feet away, and it just made him mad. He swam off. Now he may have been sore the next morning, but at the time it didn't even slow him down. I was underwhelmed with the shot shells.
Had better luck with a 125-gr. .357 SP. Didn't actually
hit the snake, but It came so close it knocked him out. We were so surprised when we couldn't find a scratch on him. Then we realized we wuz handling a live water moccasin that could wake up at any instant and
not be a good mood. He did wake up a short time after we set him down, but there was enough concentrated fire that he didn't get very far.
Sorry. I digressed from shootin' fish. Can't say I've actually
tried shootin' one. It sounds like it would be fun, however. You'd kinda have to be high up so you could sees 'em in the water better. And also so ya wouldn't ricochet.
