There is one thing that I've noticed when an NPC is equipped with a weapon that is only burst fire only or explosion damage (I modded shotguns for this for the spread effect) that they'll switch weapons when someone in their party is right next to their opponent (say Sulik is shooting at a gecko and Vic is next to it.) What causes them to do this? A thing in the script files? Is there a way to change this behavior? Sometimes that's annoying when I want to do mass devastation with a large group of surrounding foes - another thing I modded, large encounters - but someone is in the way and they cheese out on me by pulling out another gun which has less desired results. Unfortunately, I'm not familiar with the scripting part of Fallout, so if that's what's required then I'm out of luck, unless it's something I can change by editing note pad, like you can with dialog and world map .txt files. Either way, I'm still curious what causes this. I know even enemies equipped with similar weapons will do this to in similar situations.
