it would seem to me that buffalo, not being critical here, was shot just a little high.
They are tough creatures to knock down in my opinion.
I took in november a .338winmag with 225grain barnes bullets, but opted for a .375H&H with a speer gran slam. Hit that sucker square and blew the top of the heart out, but still took him a while to stop using oxygen.
I did see a .338 used on a couple of them and it did work, as well as a .300H&H
