I've wondered the same thing. After watching the footage of some of these drone intercepts I realized the camera view interceptors are very erratic. My guess is that shooting a drone down from another cheap interceptor drone is just too difficult to do reliably. I understand that the cost of the interceptors are preferable than the cost of letting them hit their targets, and I understand that they are still an order of magnitude cheaper than the long-range Geran drones they are shooting down.
Given that they show footage of men shooting down similar drones from airplanes, perhaps they can eventually build a larger more stable platform with a more reliable aim using projectiles.
