All this doinking about with the 41 Rem Mag and the 414 Super Mag has opened my mind up just a teensy bit. The 303 Savage shares similar rim and head size to the 41. Now let us consider the 375 Winchester, nice case, a little over 2" in length. Chambered in the Contender.
41 Rem Mag : 1.285"
414 Super Mag : 1.610"
414 Savage : 2.020"
Where did the moniker "414 Savage" come from? Think of the 38-55, and the updated "375 Winchester"
