Copyed this post from a really long time ago. Hope this helps some.
oh, and this is from frantic.^
Part I: Spraying Patterns
What Is Weapon Spray?
Weapon spray is a term used for when you fire repeated rounds from a gun & spray fire in a direction. By holding down the fire button and aiming straight the recoil from the weapon produces a spray of fire which hits around the target or cross hair in this case. The more recoil on a weapon the more spray is produced and this is where I come in... Unknown to many, CSS has built in spray patterns for every weapon and it's key to know the patterns if you are to take advanage of this. Note the following patterns are produced from a static firing position and when moving will change.
M4a1
You can clearly see the M4a1 has 2 main patterns a 'T' shaped pattern & a 'P' pattern that somtimes is reversed
AUG & SG550
You can clearly see with the CT's AUG & the T's SG550 both have the same spray patterns. The main spray patterns is a 'T' shaped pattern & the odd 'P' pattern slipped in.
AK47
The AK47 seems to have the same basic spray pattern every time, the first 3 rounds hit almost spot on target but after that the weapon recoil kicks in and forces the fire upwards where the remain shots hit in a large area.
Famas
When doing this test the biggest surprise although thinking about it we should have known this anyway is the CT's Famas. It has a 'Burst Fire' mode and boy j00 when you enable it and spray fire the result you get is outstanding!! The spray pattern is very small almost spot on aim. Like the other weapons players need to learn how to burst fire to over come the weapon recoil this mode on the Famas does just that.
Part II: Shooting Methods
Controlling your shot
The first step in controlling your shot is having your cross hair at the correct position. When moving around the map, your cross hair should remain at head level, and be positioned exactly where your enemies heads will appear. This lessens the time you will have to spend aiming.
The way you shoot your weapon depends both on the type of gun it is, and also the distance. For this reason, I will talk about individual weapons, and how to shoot them at different distances, starting with the pistols.
Short range would be top of stairs on dust2 to bottom of stairs
Medium range is from B double doors on dust2 to where the terrorists enter the site.
Long range is top of long a to pit.
GLOCK
Short range, enemies has no armor: My preference here is to circle them while quickly tapping the fire button. The glock has almost no recoil at close range, and if you hit them in the head they won't be able to fire.
Short range, armor: What my team normally did on save rounds without deagles was the monkey jump. You go to some part of the map where the CTs are forced into close quarters combat, then you burst fire your glocks while jumping.
Medium range: You can still quickly tap on the fire button, but you should avoid moving too much
Long range: The glock sucks at this distance. If the enemies has armor, it can do as little as 3 damage a hit. Try to get closer, either by running towards them while snaking back and forth, or by finding another point of entry. If you must shoot from this distance, duck and space your shots by about 1/2 a second. You must aim for the head, or else you will never kill them
USP
Short range: You can move a bit. If you are aiming for the head, space your shots by about 1/3 of a second. If you aim for the body, spam your shots as fast as possible.
Medium range: Stand still, possibly duck if you do not need the mobility. Shots should be fired at about 1 a second, aiming for the head. If you do spam the USP, your cross hair should be on the low part of their chest as you reach the end of your spam.
Long range: Same as medium, but don't spray. Take time to count out a second between shots (in your head, not out loud unless you want your teammates to kill you).
DEAGLE
Short range: You can strafe around them. If your first shot misses, you should lower your aim to their shoulders. If you don't get them in the first two shots, spray your deagle at their body.
Medium range: Don't move, either strafe back and forth and fire shots on the pauses, or duck for maximum accuracy. Shots should be paced at about a second each. Take the time to aim before shooting.
Long range: You cannot kill with a single shot at very long ranges, and body shots will take 4 or more to kill. Try to get closer, or if you must shoot from such a distance, duck
COLT
Short range: You can run and shoot the first 5-10 bullets of your spray, then you should duck and finish the spray. When doing an extended spray, pull your cross hair to around their navel, and wiggle your mouse back and forth.
Medium range: You can usually run with the first 3 bullets, but no more then that. I recommend that you do not move at all. Spray about 5 bullets, strafe to your left or right, then duck spray the rest of your bullets if you need to. Once again, wiggle your mouse while spraying.
Long range: Strafe back and forth while shooting 3 shot bursts. It is possible to spray at this range, but only if you have very good control, and even then it is not that accurate.
AK-47
Short range: Same as colt, but you have to pull down farther, and shouldn't move while shooting except the first 3 bullets.
Medium range: Don't move. Start with a standing spray for your first 5, then duck to pull your shot into their head and wiggle your cross hair around their kneecaps.
Long range: same as colt, but no spraying
