Every gun has different damage per bullet depending where you hit them.
Could also be the poor server tick rates too. I read they were 12hz but that was maybe on console.
I see. But sometimes when I watch the replay and see when I am getting shafted by a weapon which is comparable to mine, i think wtf?
Tick rates? Forgot about this, so if its 12hz, then this means....83ms, quite long no?
