So, revisiting this thing a bit. We have a Scatter Gun, using the basic shot gun rules.
Easy enough, no Dodge bonus, which is a good thing for the Scatter Gun user.
Scatter Gun also has an option for LOTS of Stum Gas rounds, so there is a nice thing to, since your Judge is normally only packing a couple of these for his Lawgiver II.
The Plasteel Baton Rounds, now that's an interesting one, since they give no damage for these little things. SO, digging through the Prog's, I'm assigning these things, a 5d6 damage, Shotgun range chart. Also giving them Armor Piercing on top of that because all they really are is a pumped up Sabot round, so for those that need a visualization, Think the opening gunfight in the Movie Alien nation.
In addition. I give the Plasteels a Door Opening ability, ala Real World shotguns. Such a tactic is easily researched via the internet, so no need to bore folks there.
I've also added the fact that the Scatter Gun using the normal Shot Rounds, will eat up Soft Cover, much like shotguns really do, while the Plasteel Baton rounds will basically Ignore soft cover completely.
NOW, the Scatter Gun in the hands of a Judge, is the big scary weapon that it should be.
