I have a few questions concerning the use of psyker powers in combat.
I can't find anything that says they get range increment decreases or increases, so I assume that means they don't get a bonus for aiming.
Do psykers suffer any penalties for aiming into melee?
Do psykers using ranged powers like Force Barrage, Biolightning, etc, when engaged in melee get attacked in the same way a character using a non-pistol ranged weapon does?
