Bullet spawning at high Player speed

Hey, when I spawn a bullet like this

 GameObject gb = (GameObject)Instantiate(GatlingBullet, Mussle.transform.position, Mussle.transform.rotation);

at high speed (from an aircraft) the bullets seem to be awfully delayed. This problem becomes the most visible when shooting while moving sideways. It almost seems like they are spawning at the wrong position meaning from a position some milliseconds ago.

Here is also the bullet script if you need it:

 transform.Translate(Vector3.forward * speed * Time.deltaTime, Space.Self);

Thank you for your help! :)
