Two things makes the MTS superior though: it's one hit kill ability and extremely superior spread when ADS. It has a 2 pellet kill that is 5.33 times longer than the Bulldog's. The Bulldog's pellet to kill range only surpasses the MtS's at a 5 pellet kill which you probably shouldn't be at most of the time. Also, it's ADS spread is an entire degree less than the Bulldog's (and is the second best in Shotgun category). I'd probably take the MtS-255 over the Bulldog to tell the truth. It's just a lot more fun to use.
