before the railgun concept, we didn't have a good way to generate enough kinetic energy for the shell to hit the target hard enough. The traditional gun powder explosion can not deliver such a high speed projectile. So as a compensation, people use explosive in the warhead to replace the iron ball shell. As a result, the kinetic energy in a traditional cannon is only for deliver the ammunition to the target, and let the explosive in the warhead to do the main damage. There are other old idea that didn't stand with their time because of similar technical limitations but regain power later. One example is the adjustable wing design for airplanes, in the original Brother Write's model, the wings were adjustable during flight, but later it was abandoned and replaced by the fix wings. Yet now this old concept has been recognized against as a better one over the fix wings.
