Raycasting Speed

Unity Engine
1

So I have a little piece of code that will raycast from my weapon and instantiate some sparks at the place the ray has hit.
The problem is my firerate, if I make a smaller fire rate like 0.1, the sparks will start to appear on different places and not only where I aim. What could be causing the problem. I don’t even know what to search for in the forums, nothing makes sence. Here’s my code:

var hit : RaycastHit;
	var dir = transform.TransformDirection (1, 0, 0);
	
if((Input.GetKey("f"))  (fireRate < Time.time))
	{
	//if we hit something
	if (Physics.Raycast (transform.position, dir, hit, 1000)) {
        point = hit.point;
		explosionRotation = Quaternion.FromToRotation(Vector3.up, hit.normal);
		if(hit.rigidbody)
		{
		hit.rigidbody.AddForceAtPosition (-hit.normal * 900, hit.point);
		Instantiate(impactMetal, hit.point, transform.rotation);
		}
		Instantiate(explosion, point, explosionRotation);
    }
	animation.Play ("shoot");
	muzzleTime = Time.time + 0.1;
	fireRate = Time.time + 0.1;

OK, I think the problem is that the weapon animates when shooting and changes it’s rotation. But how would I fix the ray to point in the distance at the center screen level all the time?

Don’t use the weapon’s .forward; use a different transform.
