I own a Griffin and Howe rifle built on what I believe is a Remington model 30 express action.
It is chambered in .333 Griffin and Howe Super Magnum which I assume is a .350 G&H mag necked down.
The boys at G&H have never heared of this cartridge and at that time of my inqiry and were not rearching gun histories for owners. The G&H number on the gun is 2257.
Any info on this out there?
