I know some one who just came back from Africa and was disappointed in the 270gr TSX out of his 375. As for the TSX as far as I am concerned is a bullet that if it was a person would have Schizoid Personality Disorder. I have had the same results he has had happen to him but on more than one occasion with the TSX on deer and hogs. Twice when using my 257Wby and once with my 300Wby.
When the TSX came out I thought it would be the next best thing to sliced bread. Well, was I ever wrong!!! When it kills it kills well, but it is not consistent and there is no telling how many animals have been hit with the TSX and the bullet just slip on out the other side because it did not open up. It took three shots to bring down this Zebra.
I do not use them any more because I work to hard on my hunts to get the game I am looking for to wonder if the bullet is going to do the job. I use the A-Frame and Partition on tough stuff and the Accubond on medium to large thin skinned and also the Sierra HPBT on small to medium thin skinned.
The A-Frame or the Partition has to date never failed me, nor has the Accubond or Sierra HPBT but I use them on the appropriate animals.
Here are some pictures of the schizophrenic nature of the TSX.
