Sporting Clays is sometimes known as "golf with a shotgun." This would be sporting clays with a golf club. This video looks legit to me - although I have been fooled before.

Besides the fact that they have only one projectile to sling at the target, these golfers have another big disadvantage: they have to look at the target, time it, then take their eye off the clay and focus on the ball to make this shot.
Notice all these pros do a great job of keeping their heads down. Good golfers make good shotgun shooters, and I bet any of these guys could really shoot if they put their minds to it.

It helps, of course, to be lucky, and to bring lots of clay targets.
