I've been eyeing the Model 94, and will be looking for one (along with a Hi-Point 9mm Carbine) at the next gun show here in Oct. Now I've searched through the forums here for as much info as I could find on the M94, and I've decided on a Winchester 30-30. Thank you, btw, for helping me to reach that decision. That leaves the question: Trapper or Ranger? More specifically, 16 inches or 20? Since the 30-30 is a rifle cartridge, I would guess that it has a lot to benefit from that extra 4" of barrel on the Ranger model. Or maybe the 30-30 has already exhausted its potential at the end of 16". I am sure there is a point of diminishing returns, and I dont know where that point is. Can anyone shed some light on the issue? Thanks.
