What would happen if you just started with a slug?

[sacrosancty]

I don't think you could deliver as much energy to it because it has such a small surface area normal to the direction of travel.

It’s really hard to get a slug Moving like that without tearing it apart. It’s easier to use the explosive to spread the force over a wider area initially but in a way that the projectile is formed by the concentration of the explosive forces mashing it all together. Weird.
