Sniper bullets not working

So, when I fire my sniper bullets they don't hit the targets that they're supposed to unless you're standing very close to the target. And if I increase the fly power it still doesn't hit the targets that are far away or the ones that are close. So how do I make it so that the bullets go where they are supposed to go? And it isn't a problem with the bullet spawn.

My sniper script:

 function Shoot () {
   audio.Play();
   CockingSound.audio.Play();
   var BulletPrefab : Rigidbody;
    BulletPrefab = Instantiate(Bullet, BarrelEnd.position, BarrelEnd.rotation);
    BulletPrefab.AddForce(BarrelEnd.forward * 10000);
    
 animation.Play("ShootM40A5");
 MuzzleLight.enabled = true;
 MuzzleImg.renderer.enabled = true;
 yield WaitForSeconds(0.1);
 MuzzleLight.enabled = false;
 MuzzleImg.renderer.enabled = false;
 
  AmmoInCurrentMag -= 1;
      CanShoot = false;
      yield WaitForSeconds(0.5);
      CanShoot = true;
 }
