I was always told not to shoot into the water. Bullets can ricochet off of water easier than any other surface.But I would imagine shot wouldn't bounce off the water. Not slob hunting but unsafe hunting.
sorry man a duck ain't worth no knowing where the shot is going to end up, if you cant grab it then net it
Now back to the topic at hand. Could swimming like this somehow aid the fish with digesting a large meal? Kind of like something is stuck in it's throat? Heimlich maneuver for pike?
