As we all know by now, the default Combat Shotgun is a worthless heap of crap, even with 100 Small Guns.

I've increased the ROF to make it as close to semi auto as the engine will allow me, increased the damage and the magazine size as well the pellet count. It'll explode pretty much anything on the lower difficulties, but you still need a full drum, maybe two, point blank, right in the face to kill a Super Mutant Overlord on Very Hard. Even Raiders and Talon Company goons still need a good couple of shots to the head point blank.

I did this to make those who like to use the Combat Shotgun more difficult opponents on the higher difficulty levels. If you have a low DR, expect to get ripped to shreds until you come across some Talon Company Armour or something similar.

The gun fires at around 1 shot every 1-1.5 seconds or so.
