Quite as hard as shooting down V1 rockets? … well, maybe so, if you’re shooting at one from the back of a small airplane with a shotgun, especially if you hit the wrong thing.
For example, have you ever heard of “tannerite”? It’s used to make reactive targets that explode when you hit them.
For fun, do a search for “tannerite videos” to see just how explosive small amounts of tannerite can be and how far away people are or should be when they shoot at it with rifles.
Now consider how close you have to be to shoot down a drone from the back of a small airplane with a shotgun while trying to hit a wing or the tail so that it can’t fly and then crashes.
You have to be pretty freaking close, right? … now, after having watched videos of people and fools shooting various amounts of tannerite, ponder what happens if you are that close and you accidentally hit a shahed drone’s 30–50 kilograms (66–110 lbs.) explosive payload.
BOOM! very up close and personal. Whether harder than shooting down V1s or not, it sounds like a hell of an adrenaline ride …well, other than the potential boom part, that is.
I guess the important factor is how much explosive weight and type these Russian drones are carrying. Once they are shooting with shotguns, I would guess the farther away they shoot from the more likelihood of hitting something that explodes. I am not sure how easy it is to pinpoint a target like a wing, tail, or more likely a propeller on a drone using a shotgun. I’ve only ever shot a 22 rifle, or a revolver.
