Hello there fellow Deathwatch fanatics! This is my first time posting on these boards and I'm kind of embarrassed because it seems like a dumb question, but one I want made clear for my too-literal-leaning mind.

Ok, so for example, let's say my nameless Deathwatch Devastator marine has a BS of 55. He takes aim at a big Tyranid and fires off a full burst of heavy bolter shells. The player rolls and gets a 23 -- that means he hit and achieved said hit with three degrees of success. Damage is stated to be 1D10+12...

[Here's where I lose myself]

...if he fired 6 shots (the RoF for the Heavy Bolter).

Does that mean that because he hit with three degrees of success, that 3 out of the 6 hit? Or did they all hit?

Do I roll 1D10+12 damage for each heavy bolt shell that hit the target (either 3 or 6)?

Maybe this is just one of those things I've overlooked in the core book, but it's bothering the hell out of me that I don't understand this. Can someone please help? Pretend I'm deaf, dumb, and blind and use small words with loud volume.

Let us analyze the situation step by step :

0) If player uses Aim action , then h e receives a bonus to BS test. Don't forget distance modifiers. But let the difficulty be 55.

1) He hit the target (Corebook p.244) in the body (Table 8-3, p.244) - by at least one bolt. 1 hit.

2) He got three additional level of success - each Degree of Success scores an extra hit - up to weapon Full Auto rate of fire. +3 hits. (Corebook p.239). Heavy bolter use all 6 bolts.

3) You roll damage separately for all 4 hits (using Table 8-2, p.239 to determine locations of additional hits).

Cool. That's the line of reasoning that I was aiming towards. I appreciate you laying it out, step by step. I can't describe how often being so clear and often literal helps in most situations.
