These were all taken with a Sako Kodiak 375 H&H with Barnes 300 Gr TSX bullets. None of the bulls made it out of sight once the first shot was fired. I shot all 3 bulls with 4 rounds each. None really needed the follow up shots, but I had a full magazine and you pay the same price for the buffalo no matter how many time you shoot him!
The loads were around 2450 fps from the 21" barrel of the Sako Kodiak.
