The Plasmadeffgun's probably also the nest ork weapon to be hit by the supersonic nerf screech. Since it will chew through anyone stupid enough to get close. the only real downside of it is that it chews through the 350 ammo and the second 350 from an ammo pack like a halfing in a pieshop. Find a buddy to be your ammo runt, or get a supply point nearby and your gud. I tend to use the Dakka Deffgun much like a point defense weapon, in that i will roam a point with one. And if you stumble across a heavy bolter and your both in the open, there's a good chance that you'll win, There's only two scenarios, maybe three where you won't win vs a ranged weapon. That's the Voice of the Emperor unique heavy bolter, that suppresses more than the regular one, the Quicksilver Bolter who's three round burst seems to ignore suppression. (At least, when I've come up against one.) The last is the most obvious. Stalker Bolter. If you see them first, chances ar you won't die. But if they see you first, and get a shot off your going to die before your wound up and firing.
