Ever since the new Core rules became available I've been trying to think of a way to simulate the all-out firefights of certain Hollywood/Hongkong action movies, in which characters created a virtual hail of lead by the really very simple means of repeatedly pulling the trigger in quick succession. I also tried to think up a way to allow "double tapping." Basically it's about the same problem: putting several shots in the same place without having to resort to ROF (which is far to powerful) or multiple actions (which are crippling).
A nice person on the HGML then suggested the following to me; you may or may not have read this, or already thought of this years ago and discarded it, perhaps for good reasons. This is not really new either, of course. But it's a nice mechanism, and it seems to work without being overpowering. It also requires players to think about where they put the bulk of their ammo, and it requires them to sometime change clips and worry about their ammo supplies, as opposed to conventional games where a single clip of ammo is usually enough to get you through the whole game. 
Allow me to introduce the HOLE rule (Hail Of Lead Equivalent), a natural companion to the WOO Factor:
Characters using semi-automatic weapons may decide to fire several shots in quick succession at the same target to increase damage and simulate the all-out firefights of action movies. With this rule it only takes one Standard Action to pull the trigger several times in quick succession. Characters may fire a number of shots equal to their (Small Arms Skill level plus Complexity rating) plus their Agility Attribute. Multiply this number by 1.5 for the total number of shots that may be fired by Characters using two pistol-type weapons at once; if two weapons with different DMs are used, calculate the total damage based on the lower DM. For each shot fired after the first one add one to the weapons Damage Modifier (as opposed to automatic weapons, which add their ROF to the Margin of Success). Two shots = DM +1, four shots = DM +3 etc. Hopefully the character brought enough ammo... the times when one never needed to change a clip are past. 
It can use a bit of tweaking; e.g. the number of shots allowed might be lower or higher, depending on the stats on which it is based, and the DM bonus might also be changed if it seems too high or too low.
