well first off dont listen to chris - he is a [modbreak]very nice person[/modbreak]

the problem is that you are aiming at the player's body.. sa-mp isnt perfect so you need to aim in front of them as they move some where. this is hard the first times but once u see damage go down in one spot u aim at, keep aiming there. this is called a hitbox.

Flaming and flaming.. you must be burning already

No, NoV was right, you must aim BEHIND the players
