I stand corrected
There's a check done for each of the 1/6th bullets that are aimed at the target (this means that ALL of them are checked with your CtH) and there's a check for the 1/6th that are not aimed - until one of them misses... So if a gun fires
n bullets per burst, the average number of bullets that hit the target will be:
(n/6)*CtH + ∑CtH^i where the sum is for i = 1 to n/6
But in Atom's post on NMA I found something curios:
When I changed ToHit to constant 100%, the primary target was hit by 334, and the two at it's sides for 333.
No bullets were wasted. So the question is how does the game round numbers?
