Actually, orion, Lawrencium wouldn't provide that much more power than plutonium... Consider, the only reason Fat Man was a bigger explosion than Little Boy was because plutonium requires a higher critical mass due to it being soft and easily molding together with plutonium that got hit at it with it... It's why they had to use the implosion design rather than the gun design that uranium could easily handle. And remember, more mass= more boom. But why try to use fission when you can use something that provides a TON more power and, unlike lawrencium, the fuel is plentiful? Fusion. And all it requires is a little hydrogen, which is the most plentiful element in the entire universe. You could also use anti-matter - matter destruction, but it uses a ton of anti matter in the process, and really isn't useful to use in a pure anti-matter bomb. Using anti-matter with hydrogen provides you the capacity to make a pure fusion weapon, though...

... A railgun actually won't do that much when dropping kenetic rods. There is this thing called the atmosphere. Once your rod reaches terminal velocity(they already do by the time they hit the ground, usually), it can't accelerate further, and if it happens high up, it's actually going to decelerate as it falls due to thickening atmosphere.
