Enemy can not see where damage is comiing from
+30 pellets
-75% spread
-50% clip size

Explosive rounds that light enemies on fire, and counts as 8 people on point capture

Stats
Pro:
33% Larger clip size
Clip based reload

Cons:
30% Less pellet count
75% Slower Reload

The round cartridge on the gun would seem to hold more bullets and reject the need to individually load the shotgun shells. However, the Scout would not be able to load the bullets as fast as the would need to remove the empty carttidge and replace it with a new one. Additionally the smaller exit on the barrel of the gun would suggest that less bullets would be able to get through. So you sacrifice (for lack of a better term) dps for more bullets and reload time for more convenient bullet storage. Simple, but not overly powerful.
