30 Carbine - Lever
Either Marlin or Mossburg made one. I'm sure someone here will know which. Actually, if you have access to cheap ammo, the 30 Carbine is a great fun gun to shoot. If you have a good stand, or are a good stalker, it would be okay for small whitetails, handloaded with good bullets, in the 50 yard range. I wouldn't personally want to stretch it out any farther.
