That's the same With me, 9.nine. I have barely any Health left even though i started firing.

It's way too OP in my opinion. They should nerf it a little, not much though. Maybe a Shorter burst or something. Like Raphael2 said, it can kill a Mammoth in one burst, which is a little bit too Over Powered really.

Its a very good weapon if you have a good spot where you are hard to see, i got something like 6 kills while standing in a bush! You should definetly get the Thunder, and if you have it, Upgrade it!
