Using Raycast to shoot a bullet sometimes goes through objects

ok so im shoting a bullet with a ray cast my GunScript instantiates the bullet then I have a script atached to the bullet that shoots it using raycast. The only problem is when I shoot it sometimes ads the bullet hole to the object in front of me sometimes it goes through.

Here is my bullet script:

 var maxDist : float = 1000000000;
 var decalHitWall : GameObject;
 var floatInFrontOfWall : float = 0.001;
 
 function Update () 
 {
     var hit : RaycastHit;
     if(Physics.Raycast (transform.position, transform.forward, hit, maxDist))
     {
         if(decalHitWall && hit.transform)
             Instantiate(decalHitWall, hit.point + (hit.normal * floatInFrontOfWall), Quaternion.LookRotation(hit.normal));
     }
     Destroy(gameObject);
 }
 
 

and here is my gun script:

 var cameraObject : GameObject;
 @HideInInspector
 var targetXRotation : float;
 @HideInInspector
 var targetYRotation : float;
 @HideInInspector
 var targetXRotationV : float;
 @HideInInspector
 var targetYRotationV : float;
 
 var rotateSpeed : float = 0.3;
 
 var holdHeight : float = -0.5;
 var holdSide : float = 0.5;
 var ratioHipHold : float = 1;
 var hipToAimSpeed : float = 0.1;
 @HideInInspector
 var ratioHipHoldV : float;
 
 var aimRatio : float = 0.4;
 
 var zoomAngle : float = 30;
 
 var fireSpeed : float = 15;
 @HideInInspector
 var waitTilNextFire : float = 0;
 var bullet : GameObject;
 var bulletSpawn : GameObject;
 
 var shootAngleRandomizationAiming : float = 5;
 var shootAngleRandomizationNotAiming : float = 15;
 
 var recoilAmount : float = 0.5;
 var recoilRecoverTime : float = 0.2;
 @HideInInspector

 @HideInInspector

 var bulletSound : GameObject;
 var muzzleFlash : GameObject;
 
 var gunbobAmountX : float = 0.5;
 var gunbobAmountY : float = 0.5;
 var currentGunbobX : float;
 var currentGunbobY : float;
 
 function LateUpdate ()
 {
     currentGunbobX = Mathf.Sin(cameraObject.GetComponent(MouseLook).headbobStepCounter) * gunbobAmountX * ratioHipHold;
     currentGunbobY = Mathf.Cos(cameraObject.GetComponent(MouseLook).headbobStepCounter * 2) * gunbobAmountY * ratioHipHold;
     
     var holdMuzzleFlash : GameObject;
     var holdSound : GameObject;
     if(Input.GetButton("Fire1"))
     {
         if(waitTilNextFire <= 0)
         {
             if(bullet)
                 Instantiate(bullet, bulletSpawn.transform.position, bulletSpawn.transform.rotation);
             if(bulletSound)
                 holdSound = Instantiate(bulletSound, bulletSpawn.transform.position, bulletSpawn.transform.rotation);
             if(muzzleFlash)
                 holdMuzzleFlash = Instantiate(muzzleFlash, bulletSpawn.transform.position, bulletSpawn.transform.rotation);
             targetXRotation += (Random.value - 0.5) * Mathf.Lerp(shootAngleRandomizationAiming, shootAngleRandomizationNotAiming, ratioHipHold);
             targetYRotation += (Random.value - 0.5) * Mathf.Lerp(shootAngleRandomizationAiming, shootAngleRandomizationNotAiming, ratioHipHold);
             currentRecoilZPos -= recoilAmount;
             waitTilNextFire = 1;
         }
     }
     waitTilNextFire -= Time.deltaTime * fireSpeed;
     
     if(holdSound)
         holdSound.transform.parent =transform;
     if(holdMuzzleFlash)
         holdMuzzleFlash.transform.parent =transform;
     
     currentRecoilZPos = Mathf.SmoothDamp(currentRecoilZPos, 0, currentRecoilZPosV, recoilRecoverTime);
 
     cameraObject.GetComponent(MouseLook).currentTargetCameraAngle = zoomAngle;
 
     if(Input.GetButton("Fire2")){
         cameraObject.GetComponent(MouseLook).currentAimRatio = aimRatio;
         ratioHipHold = Mathf.SmoothDamp(ratioHipHold, 0, ratioHipHoldV, hipToAimSpeed);}
     if(Input.GetButton("Fire2") == false){
         cameraObject.GetComponent(MouseLook).currentAimRatio = 1;
         ratioHipHold = Mathf.SmoothDamp(ratioHipHold, 1, ratioHipHoldV, hipToAimSpeed);}
     
     
     transform.position = cameraObject.transform.position + (Quaternion.Euler(0, targetYRotation, 0) * Vector3(holdSide * ratioHipHold + currentGunbobX, holdHeight * ratioHipHold + currentGunbobY, 0) + Quaternion.Euler(targetXRotation, targetYRotation, 0) * Vector3(0, 0, currentRecoilZPos));
     
     targetXRotation = Mathf.SmoothDamp(targetXRotation, cameraObject.GetComponent(MouseLook).xRotation, targetXRotationV, rotateSpeed);
     targetYRotation = Mathf.SmoothDamp(targetYRotation, cameraObject.GetComponent(MouseLook).yRotation, targetYRotationV, rotateSpeed);
     
     transform.rotation = Quaternion.Euler(targetXRotation, targetYRotation, 0);
 }

What am I doing wrong?
