Maximum ROF, Ideas Options

[Lilt]

How fast do RL guns fire if the trigger is just held down? I'm just wondering about adding more rules for full-auto fire, saying that the current rules reflect extended, aimed, bursts rather than genuinely holding the trigger down constantly.

This idea was spawned from the 4+ actions per CT thread, and goes against the idea that characters with high initiative can somehow make their guns work faster.

Essentially: Put a maximum ROF per combat round on guns with FA modes. From a bit of snooping around about modern assault rifles, most of themn seem to sit at around 600-800RPM with a few reaching 1000+. that translates into about 30-40 or possibly 50 rounds per combat turn.

My idea is to assign a maximum ROF per CT number to guns (probably 40 for FA-capible guns) and say that:
a) no character, even mr 8 actions Night-One w/MBW-4 can shoot more bullets than that per CT
b) any character, even bob the 4+1d6 kidd. can spend a whole combat turn hosing an area with true full-auto fire, but they must use a variant of the suppressive fire rules where the number of bullets allocated to an area are divided by 4 and considered present in the area for the whole combat turn (and add another +2 or so modifier)

Is that horrendously broken? I'm know I'm trying to make sense of an abstract system, but I think it can be made to work...
