Emptying a whole magazine doesn't land one lethal shot

Might sound like im just bitching (I kind of am) but hitreg (if that is the issue) is a major problem. I was playing a game on summit (I think) and i found a guy in the corner. Naturally, I held mouse1 at his body, but apparently none of the shots in a 30 round mag where enough to kill the guy (he was ~3 meters away). He shot at me a couple times and I died within 5 bullets.

@pieck the time to kill has been increased, for whatever fucking reason. But still, a lot of people are reporting hit reg problems also
