I actually tried this during Doubles and it set my ammo to 0 when I switched weapons, surprisingly - was only expecting to lose half. Yet for some reason it still works with Sidearms? They really should get on this nonsense. EDIT: Sniping with Icebreaker isn't even that hard, I actually do pretty well with it. Fact: It has fairly decent AA due to it's maxed range and does more body damage than the stare.
