First off, yeah, shotties need more ammo choices. Secondly, to h*** with buckshot if you're talking about close ranges. Birdshot is where it's at up close. It transfers more of the kinetic energy from one round into a nice tight area. Basically, -1 AP, +1 Dam. Buckshot would be the opposite, +1 AP, -1 Dam. And shotguns firing slugs would just be nasty. Wouldn't deal with the normal flechette AP modifications for normal shotgun rounds, but still doing the same damage as a normal shotgun round. Soaked by ballistic armor. And that's just the start of what you can do with shotguns. Sawing them off makes the less accurate over distance, but makes them more concealable. Different gauges of shotguns exist, and I would hate to see what the damage would be on a 10 gauge. Most of the shotguns in the rules seem to be 12 or 14 gauge barrels. Also, let's not forget that in our world right now, there are military shotgun rounds that are basically tiny explosive missals. Look them up, they are called Frag-12 shotgun ammunition. Fin-stabilized, high explosive armor penetrating shotgun shells. Nasty buggers from what the military is saying. To h*** with rules for dragonsbreath. I want those in game!
