brain storm

So upon looking at the gun again, I realized that I could give it two types of shells to use for ammo. A solid howitzer round, and a shotgun-esque shell with multiple smaller bullets. For the shotgun shells, I'll probably use the metal storm tech idea that the Australians have developed, implementing a firing delay for the last round as the rest of the shell casing holding the explosive rounds goes out with it as a regular metallic slug.
