Perhaps such inefficient dumping of energy into air could knock drones out of the air.

“Shells did not hit planes, but sprayed them with high-velocity shrapnel fragments.”

Even if railguns are not the answer, conventional flak cannons might work. A cannon or rocket could deliver a “flak” warhead to the general vicinity of the target drone. Because it is not necessary to score a direct hit, an explosive warhead could be detonated some distance away from the drone, but the shockwave might be sufficient to kill the drone. Perhaps the problem is that the artillerists might have to fire 20,000 flak shells to down one drone.
