Twice this season I had heat monkeys dancing on my barrel to the point I could not see the next bird well enough to get a bead on it. If I had one of those, the heat monkeys would be blazing inferno gorillas and skeetshooter wouldn't be able to see either!

Realistically you can only shoot one shell at a time. Unless you call down to Baton rouge Louisiana, Red Crapet firearms and order you a rotating 12ga, that way you can shoot there shells at once.
