Gatling guns in shadowrun are basically machine guns that fires about 50% faster. However, this is far from reflecting what a real gatling gun is capable of doing, being able to shoot literally hundreds of bullets of seconds.
What I expect here isn't a houserule proposition be rather a discussion on how they could work in this game, when completely disregarding the obvious balance issue.

Let's say I have a minigun, with a potential firing rate of 50 rounds pet bursts and a base damage of, well... whatever. Let's say base damage of 8. Let's imagine that the recoil is also manageable in some way or another.

Now, this weapon, according to the base rules, would either obliterate the target or leave it unscratched because of the nature of armor. Indeed, I don't see many things capable of soaking 58 points of damage each rounds. However, depending on the user's skill, the damage might be downgraded to stun damage (which would still obliterate a living target, but do basically nothing to an object).

To anyone that actually deciphered my horrible english, I ask: how would you work this around?

PS: disregard balance issue, I just want a logical "fix" that fits within the general mindset of the rules.
