|*|Regarding the hit bonus, the +10% accuracy does indeed stack. The maximum amount of extra-accuracy you can gain is 70%. If you hit someone and stop hitting them for at least 4 seconds, the buff will wear off. So if you shoot a heavy 3 times, you get +30% accuracy, then you run away which takes 4 seconds and the +30% accuracy wears off. You are then left with the normal gun with no bonus.

How about:
-50% fewer pellets per shot
-100% more damage per pellet
-X% less pellet spread
-2 fewer shots per clip
-20% slower firing speed
The stats basically give the pyro/engi/soldier/heavy a secondary (primary for the engi) that encourages more deliberate shots to do more damage at medium range. The 100% extra damage per pellet might seem outrageous but if you consider that the stock shotty does about 6 damage per pellet (give or take) and it fires 10 pellets, totalling 60 damage if all pellets hit. The 100% increase in pellet damage means that each pellet does 12 damage (give or take) and with 50% fewer pellets (total of 5 pellets) means that the shot will still do 60 damage in total.
