the splatmaster was not a pump, it was a rear bolt cocking mechanism, only used 12 gram CO2 and had a 10 shot max fill. So all that in consideration, make sure you aim and keep spare CO2 with you. I would make the setup for the splatmaster to this spec for some real hard game playing. Heck if you made it I would gladly make a map I think it would go good with. It would bring some of the "make your shots count" rules in paintball here.
Side Note: I also have a render for the old classic "cigar tube" 10 shot fill to go with this as well instead of the 40+ boxes. I like DP2 so much this is why I thought to add this classic gun as well. Kick it around a bit, think about it some, I sure would like to toy with it.
