Can I play two different animations on one button?

I have a rifle with a mag attached. After each shot I press "R" to reload (and play animation "Reload") 10 times until the mag is empty. Then by pressing the button "R" again it should play "Empty" animation and change the mag but it doesn't play anything. Can you please help me? Here I've written few lines, maybe I can add something to make it work:

     private int currentAmmo;
     void GetButtons()
         {
             reload = Input.GetKeyDown(KeyCode.R);
 void Update()
         {
             anim.SetBool(hashs.emptyHash, empty);
             if (currentAmmo <= 0)
                     {
                         if (Input.GetKeyDown(KeyCode.R))
                         {
                             anim.Play("Empty");
                         }
                     }
