tutorial

Laying the bullet first is important for high recoil guns, such as AK47, SCAR.
Depending on your style, end it within 1 ~ 3 bullets (Max) for high recoil guns against expert players. Or else, most likely you are dead.

2nd, is the low recoil guns, such as HK416.
It is not require to land the bullet first, but you need a stable aiming in order to deal a better damage. Those guns are easier to use.

Just a little tip for non-subzero. It is a better choice for you to use HK416, as it doesn't not require much skills compared to those guns.

Crosshair and Mouse sensitivity

Crosshair

A general guideline here:

Crosshair A is a balance between accuracy and recoil. Best used to master moving accuracy and to get a feel of the weapon's standstill accuracy, recoil and timing (especially SCAR and AK-47). Personally it is my favourite choice for all weapons.

Crosshair B is more accurate in close ranges but may not fare so well in long ranges due to the smaller area covered with its thick crosshair (which may obstruct your vision in long distances).

Crosshair C = max out recoil spread.

Crosshair D = same as B but with much more emphasis on recoil.

Crosshair E = Pinpoint accuracy, great over long distances and pre-aiming with your AK-47 / SCAR across small gaps. However you should first master the weapon before moving on to this.

Mouse Sensitivity

Different people different mouse, different preferences, different playstyle. Sniper players usually have low sensitivities where as knifers have really high sensitivity.

DPI of a mouse & windows pointer sensitivity plays a part too. (so does the X & Y axis if you own a better mouse with drivers)

To me, benefits of low sensitivity user = stable aim, pin point accuracy, easier for crosshair to 'follow'
High sensitivity user = fast swipes, easy to do 180 degree or sharp turns, easier to counter enemies coming from the back

I came from a slightly high sensitivity user and came to a decision that i preferred lower sensitivity for its accuracy. I am now required to perform 2-3 swipes across my 15-inch mousepad to do a 180 degree turn, thats the sacrifice made for accuracy.
