Shooting in the LookAt direction

HI!

So at the moment i have a simple script which determines the direction of a bullet using AddForce:

 var bulletSpeed : float = 200.0;
 
 function Update () {
 
     rigidbody.AddForce(Vector3(bulletSpeed, 0, 0));
     
 }

I also use a simple LookAt script for my 'gun' to look at an object variable:

 var myTarget : Transform;
 
 function Update () {
 
 transform.LookAt(myTarget);
 
 }

All i want is for my bullet to travel in the same direction as the LookAt...is this possible?

Thanks, Tom :)
