And each group of bullet holes are different attempts at firing the weapon correct? Funny thing is, it looks the same way with CS:S.
Let me get on CS:S and take some screen shots.
Here they are:
I used the same guns as you did.
AK-47
M4
The red arrow is where I starting shooting. Now even though 1.6 has more upward recoil (though it seems) the bullet pattern looks similar in both versions. Plus CS:S has better graphics, better in game upgrades, more people, and less cheaters so either way I still say CS:S wins.
