Often what is legal in one state is not legal in another...

Used properly, in a shotgun that has been pattered, buckshot is lethal out to about 40 yards, I have killed at least 30 deer with buckshot...Just like sighting in a rifle, you have to try different brands of ammo, different size shot and in a shotgun even different chokes...

Many who turn their noses up at buckshot have never tried it on game...
