Bullet facing

Hey! I want to make my bullets that exist revolve around a place when it is clicked but the the bullets always revole around the same place. I have this code in the spawner to give directions:

 using UnityEngine;
 
 public class FireScript : MonoBehaviour 
 {
     public float hitx = 0;
     public float hity = 0;
     public float hitz = 0;
     public Vector3 hit1 = new Vector3 (0, 0, 0);
     public GameObject Bullet;
     public Vector3 hit3;
 
     void Update() 
     {
         if(Input.GetButtonDown("Fire1"))
         {
             Ray ray;
             RaycastHit hit;
             ray = Camera.main.ScreenPointToRay(Input.mousePosition);
             if (Physics.Raycast(ray, out hit, 100.0f))
             {
                 GameObject bullet = Instantiate (Bullet, transform.position, Quaternion.identity) as GameObject;
                 if (hit.collider.name == "S_Plane") {
                     hit1 = new Vector3 (hit.point.x, hit.point.y, hit.point.z);
                     BulletShootScript bulletScript = bullet.GetComponent<BulletShootScript> ();
                     bulletScript.hitx2 = hit.point.x;
                     bulletScript.hity2 = hit.point.y;
                     bulletScript.hitz2 = hit.point.z;
                 
                 }
             }
         }
     
 
         }
     }
 

And this code in the bullets:

 using UnityEngine;
 using System.Collections;
 
 public class BulletShootScript : MonoBehaviour {
 
     Vector3 ShootPos = new Vector3(0, 0, 0);
     public float hitx2 = 0;
     public float hity2 = 0;
     public float hitz2 = 0;
     public Rigidbody rb;
     public FireScript fs;
     // Use this for initialization
     void Start () {
         rb = GetComponent<Rigidbody>();
         fs = GetComponent<FireScript>();
         rb.AddForce( transform.forward * 100 );
 
 
 
     }
     
     // Update is called once per frame
     void Update () {
         Vector3 hit2 = new Vector3 (hitx2, hity2, hitz2);
 
         Quaternion rotation = Quaternion.LookRotation(hit2 - transform.position);
         transform.rotation = rotation;
         rb.AddForce( transform.forward * 100 );
 
 
     }
 }
 

Can somebody please help me?
