I'm reasonably good with clay targets. I would expect that if I was actually asked to take on drones I would need to do some practice on drones before I'd be good at them too. Drones are more expensive than clay targets but they're not particularly expensive and considering the situation I'd be willing to pay the price of a few drones to learn how to shoot them down down in a controlled setting where it's safe.

Shotguns have very short range: if I'm expected to be taking down a drone with a shotgun things are really bad at that point my life is alread in danger. if I hit I may save my life.
