Because a rapid-fire pie launcher just isn't enough.
My gun would be a rail gun that accelerates two projectiles, the first containing plutonium and the second being a tiny ball of neutrons. On impact the former ejects the plutonium out the back to collide with the following neutron detonator. Playing hard and fast with the laws of physics to make a nuclear gun seems worth it.
