I only seen one grand Alaskan and I am pretty sure it was a 1:32. Maybe we should ask if any other DWB knows for sure. Could confirm with Doc but sometimes it takes a while to hear back from him . The Grand Alaskan was basically a 54 cal super 91 with a heavy barrel. I remember Doc talking about how accurate it was with 750 gr conical and 200 gr powder if you want a gun for African hunt .
