(Raycasts) C# Why am I shooting myself?

This is the offending function. I thought it was working correctly, but sometimes the weapon will hit the Player even though I have a layer mask set up.

     public float SpreadAngle;

     void ShootGun()
     {
         RaycastHit hit;
         // Finding the fire angle
         Quaternion fireRotation = Quaternion.Euler(new Vector3(GameObject.Find("Camera").transform.eulerAngles.x, transform.eulerAngles.y, 0));
         Quaternion randomRotation = Random.rotation;
         fireRotation = Quaternion.RotateTowards(fireRotation, randomRotation, Random.Range(0.0f, SpreadAngle));
         // If the ray hits something
         if (Physics.Raycast(transform.position, fireRotation * Vector3.forward, out hit, mask))
         {
             Debug.DrawLine(transform.position, hit.point);
             Debug.Log("Raycast from " + transform.position + fireRotation + " hit " + hit.transform.name + " at " +  hit.point);
             if (hit.transform.tag == "Enemy")
             {
                 hit.transform.GetComponent<Scr_Health>()._Damage(Damage);
             }
             GameObject hitmarker = Instantiate(HitMarker, hit.point, Quaternion.LookRotation(hit.normal));
             Destroy(hitmarker, 1);
         }
     }

Here are some of the debug messages I've been getting. It appears to only be a problem with a specific angle.
