I'm still waiting for coilgun artillery to take off. No need for charges to fire, rail itself can be relatively unprecise, as long as the shell head can glide bomb the flight trajectory to target. Rest of the shell body could be a small distribution charge and some vacuum compressed peeble. Or just do away with traditional artillery altogether and electrically gun up small gun cotton glider drones, that circle above target areas until they receive a drop and kill order.
