By gathering some funny rules, I managed to create some kind of monstrosity of a gun I like to call the "Metalstorm" :
Big Shoota (Core Rulebook p128 or Into the Storm p143)
+Kombi-Shoota ( Twin-Linked ) (Into the Storm p143)
+Ekstra Barrulz ( Storm , Innacurate , -5BS if weapon is already innacurate) (Hostile Acquisitions p59)
+More Dakka (additionnal success when fired on semi- or full-auto, uses twice the amount of ammunition)
The results are : the Big Shoota only has a clip of 40, and a full-auto RoF of 10. When shooting, every shot counts quadruple because of Twin-Linked and Storm , and the consumption is again doubled because of More Dakka, thus consuming 80 ammo while there is only 40 in the clip. (the whole problem could be circumvented by installing a Bigga Klip, but we'll come back to that later)
What would be the consequences of such madness, except wet pants among the ranks of whoever is on the other side of your barrulz when you sneeze and admiration of your fellow kinsmen ?
My guess would be that there could never be more than 20 hits whatever the results of your dices (because More Dakka dictates that half your ammunition is basically wasted when shooting), but who will ever score that many success on a roll anyway, especially with an Ork?
i.e. Krazy Mekano has 45 BS (which can be considered marksman accuracy amongst all orks) and squeezes the trigger for a full-auto burst at a bunch of unfortunate snotlings rummaging at the test range at the wrong time :
The Ballistic Test becomes 45 +20 (full-auto) +20 (twin-linked) -5 (for Ekstra Barrulz).
Krazy throws a lucky 04 on his D100.
Which means he scores 8+1 successes (thanks to More Dakka), which translates into 9 hits,
then Twin-Linked adds +1 hit because he scored more than 2 degrees of success (I'm not sure if I should add 1 hit for every two success though, but let's take the exact words on the Twin-Linked rule for this example)
and finally Storm doubles the amount of hits inflicted on the target
Total hits : (9+1)x2 = 20 Hits (remember this is a pretty extreme best case scenario).
Theoretical ammo spent : 10x2(twin-linked)x2(storm)x2(more dakka) = 80 (but there is only 40 in the clip)
The big question is : what would be the major difference if I decided to add a Bigga Clip to match the clip with the ammo consumption?
Also did you notice anything wrong in my interpretations of the rules?
