I'm heading out with a buddy tomorrow for a 12 day fly-in/float hunt to fill a bison tag I was lucky enough to draw. I will be using my Marlin 45-70 guide gun to slay the beast. I'll be shooting the RCBS 45-405-FN (#2 alloy). Moose, Grizzly bear, Black Bear and Wolf are also open and good possibilities. Wish me luck.
