Unity3D grenade not exploding correctly

So I have my grenade script, and its working but not great. I got my ragdoll that Im testing the grenades on and that ragdoll is moving in the direction that Im throwing from, even if I throw a grenade infront of him and Im standing behind him, he is moving forward...How can I make this so he moves in the direction depending on where the bomb is?

 public class GrenadeThrow : MonoBehaviour 
 {
     public Rigidbody Grenade;
     public Transform GrenadeBarrel;
     public float timeBetweenShots = 0.03f; 
     private float timestamp;
     public int GrenadeAmmo = 5;
     public float radius = 5.0F;
     public float power = 10.0F;
     
     
     
     void Update () 
     {
         if (GrenadeAmmo > 0) 
         {
             if (Input.GetKeyDown (KeyCode.G)) 
             {
                 Rigidbody GrenadeInstance;
                 GrenadeInstance = Instantiate(Grenade, GrenadeBarrel.position, GrenadeBarrel.rotation) as Rigidbody;
                 GrenadeInstance.AddForce(GrenadeBarrel.forward * 700);
                 Invoke("Explosion", 2);
                 timestamp = Time.time + timeBetweenShots;
                 GrenadeAmmo--;
             }    
         }
     }
     public void Explosion()
     {
         Vector3 explosionPos = transform.position;
         Collider[] colliders = Physics.OverlapSphere(explosionPos, radius);
         foreach (Collider hit in colliders) 
         {
             if (hit && hit.rigidbody)
                 hit.rigidbody.AddExplosionForce(power, explosionPos, radius, 3.0F);
             
         }
         
     }
 }

I have checked the Unity Script Reference, and thats where I got the "Exploding" part from. And there is one more thing, the explosion has no effect on the ragdoll if Im standing far away and the bomb lands next to him, but if I walk up with my FPS controller next to him and throw a bomb AT THE SAME PLACE, it blows the ragdoll away...
