Hornady customer service wants the remaining ammo back to check it out and will replace it. Pretty darn good. I can empty the cylinder and fire other ammo with no problems and the put the Empty lever evolution cases back in the cylinder and my pistol will hang up. it will not rotate with these cases. I know its not a good idea but I put unfired lever ammo in it and it rotates just fine ,being very carefull while letting the hammer down.
