Is it that spurt cannons fire multiple rounds per trigger or empty the entire mag in a single run? wondering as I am going to be building one for the Shimakaze now and build methods change depending on which it is. If you can have the gun empty the entire tube in one run can you split a single unit into 2 provided that the ship had twin guns in said point?(space providing and whatnot). never mind reread the rules and both seem to be true. so i go into how do you make it so that your cannons regularly spurt 4-5 bb per trigger instead of 1 or is it best to just have it like a 2 bore shotgun at 10 bb's each?
