400g TSX for the first shot, solids thereafter. Brief version: It was hit very hard with the first shot, went maybe 40 yards and stopped. Hit with the second shot and was down in about 20 yards. A third shot in the top of the spine to seal the deal.
He was a good buffalo, 38-39". As it was getting close to the end of the season I was able to get a decent deal on a second buffalo and got one I like even more.
