RE: Favorite Bison Cartridge?
 

After recommendations to go for a head shot to put thebison down versus possibly having it run to the bottom of a steep river bed with a lung shot, I changed from my ironsighted 45/70 to a scoped Ruger #3 in 30/40 Krag. Needless to say, I still had to go for a body shot at around 200 yds. A 180 grn. took out a front leg and the heart and the buff didn't go ten feet before going down. I would still prefer a bigger bullet though.
