aiming a paintball gun is fairly hard to do whe nyou first start out. you will want to (according to your right or left handed nature) hold it straight up in front of you pointing in front of you. then tilt the gun to the left or the right (whichever is more comfortable for you). THIS IS FOR SPEEDBALL GUNS. IF YOU HAVE A SCENARIO GUN YOU WILL WANT TO SHOOT IT NORMALLY THEN AIM FROM SIGHT. since the hopper will be in the way, I would just tilt it slightly then shoot a shot and aim from where that shot gopes.
hope it helped :D
Aim & shoot.. Shoot first & ask questions later..
