Great hunt and a very nice buffalo. Gotta love that Ruger 375. My gun of choice on my hunt and I used the same ammo combo you did. A frames are devastating. Congrats to all.
Nathan recommended the A-frames. After seeing the thickness of the Buffalo's skin I understood why one needed an exceptionally tough bullet. They really are devastating - both buffalo were pretty squarely toward me and the impact of the a-frame almost knocked them down. I never imagined that would have that effect!
