Proper way to Pool Object - Can't acces due to protection level

Hello everyone, I wanted to corroborate the way Im creating a "bullet" pool.

So, I've attached a script to a static object. Where it gets mouseInput from the user. As soon as its clicked it creates an object.

Here's part of the Script

 public GameObject object2Spawn;
 public bulletActions projectile;
 
 void Update () 
     {
 
         if(Input.GetMouseButtonDown(1))
         {
             //Some variables I've deleted to make this shorter.(They're not the problem)
 
          projectile = ObjectPoolManager.CreatePooled( object2Spawn, transform.position, player.transform.rotation ).GetComponent<bulletActions>();
             projectile.GetComponent<bulletActions>().moveTowards(userInputPosition);
 
         }
     }

And here's bulletActions script

 public class bulletActions : MonoBehaviour {
 
     float moveSpeed = 0.5f;
 
     // Use this for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
     void Update () {
     
     }
 
     void OnTriggerEnter (Collider other) {
 
         Debug.Log ("OnTrigger");
         Debug.Log (collider.gameObject.name);
         Destroy(this.gameObject);
         Destroy (other.gameObject);
 
         }
 
 
     void moveTowards (Vector3 direction) 
     {
 
         transform.position = Vector3.Lerp(transform.position, direction, moveSpeed);
     }
 
 }

I think its a fairly simple script, added a bounding box that tells that if it collides with something else, destroy it.

Now. I've got 2 issues. I got a script from the forums that instantiates and manages pooled objects. From here:

1-http://forum.unity3d.com/threads/34582-Stop-wasting-memory-recycle-your-objects! And I don't know if Im creating the pooled object correctly.

2-Im trying to access 'bulletActions' method called MoveTowards like this "projectile.GetComponent().moveTowards(userInputPosition);" but Im getting this error bulletActions.MoveTowards(Unity.Engine Vector3)' is inaccessible due to its protection level.

Am I properly casting the first issue && how do I solve my second issue!? help please!!!
