Create the blood particles to splash blood upwards, set OneShot and Auto Destruct, and drag it to the Project panel to make it a prefab. If you are shooting the enemy with Raycast, instantiate the particles in the shooting script this way:

var bloodPrefab: GameObject; // drag the blood prefab here

...
    if (Physics.Raycast(ray, hit)){ // when you shoot...
      if (hit.transform.tag == "Enemy"){ // and hit an enemy...
        // find the necessary rotation...
        var rot = Quaternion.FromToRotation(Vector3.up, hit.normal);
        Instantiate(bloodPrefab, hit.point, rot); // and make the enemy bleed
      }
    }

But if you are hitting the enemy with instantiated projectiles, add this code to the projectile script:

var bloodPrefab: GameObject; // drag the blood prefab here

function OnCollisionEnter(col: Collision){
  if (col.transform.tag == "Enemy"){
    var contact = col.contacts[0]; // get the first contact point info
    // find the necessary rotation...
    var rot = Quaternion.FromToRotation(Vector3.up, contact.normal);
    Instantiate(bloodPrefab, contact.point, rot); // and make the enemy bleed
  }
  Destroy(gameObject); // destroy the projectile
}

Yep, that’s definitely how it works. Is it displaying the right number now?
