Revision of my earlier post:
Rename the current Elephant Gun assembly to "
Punt Gun". Create a new assembly from a shotgun that converts it to a rifle, named "elephant gun" (possibly BP). IRL, elephant guns are rifles, not shotguns, and punt guns are the largest shotguns, so I think the change would be appropriate.
Buckshot was intended to still be a shotgun, but have the damage type changed to bullet to help it pierce protection better.
Dragon's breath using fire damage would allow for easier gibbing of enemies, as well as destroying walls and corpses (?). Also, the assembly provides a use for firestorm packs on shotgun builds.
Sawed-Off shotguns wouldn't work with double shotguns, and I don't really care/have a good idea of which mods would be best for it.
New knife ideas: (again, some may have already been proposed)
