blood angles --- Sanguinary guard, with Commander Dante to make them troops. there shooting is short but they are 2+ jump troops - get a preast n they go feel-no-pain
grey nights have some great shooting. n if I think you are talking about the same book im thinking about

taking some really shooty golden grey nights would be spot on for attachments like the dread night or a few venerable dreadnought with 2 twin-linked
str 8 auto-cannons with a total of 4 shots XD
... what is the book?
