Bulletproof People?

I have this little problem when playing crossfire. I try to shoot people (as the general purpose of the game) and I can't hurt players even by 1hp most of the time. I aim the cross-hair at the enemy and shoot, but the cross-hair doesn't turn red, and after I use up the clip the enemy kills me and I see in the info that I didn't even hurt him by one hp. Sometimes the cross-hair turns red and back to green intermittently and after I die I only hurt the enemy up to like 60hp. This makes it impossible to play the game.

My status usually varies anywhere from 50 to 150 but most of the time its from 50-70. On rare occasions I've seen it go up to 150 but that doesn't happen often. The scenario I just described happens on 50+ status (which I think is another word for "ping" or "connection quality").

It gets quite frustrating that it takes me like 2-3 clips to kill someone because it doesn't register my bullets or something. I do, in fact, aim the cross-hair at the enemy and most of the time it doesn't hit the enemy. If I had some software to record my gameplay as proof of what I'm saying (or to just clarify it) I would, but I don't know of any free ones. If any of you guys do, that would be nice.

The playback option (the thing you can save after the game) doesn't show the cross-hair and the viewer kind of has to guess where it's at (If I remember correctly, haven't played back any games recently).
