Long toms can use special munitions. There's the Davy Crockett-M ammunition for Long Toms. But that blast is waaaay too small for a nuke, so I guess it's just a conventional round, just a bit more powerful. Big explosions generate mushroom clouds due to the physics of superheated gases.

You'd be surprised at how small you can get a nuclear weapon. The M-388's W54 warhead was a sub-kiloton tactical warhead capable of being dialed down to a mere 10 ton yield. It was only lethal to about 250m IIRC, and that was only because of the gamma burst upon detonation.
Also, just a side note, modern 250lb bombs can create a mushroom cloud upon detonation. It's not *big* warheads, it's *powerful* warheads that generate mushroom clouds.
