I managed to recover a TSX bullet from the brown bear I shot last Saturday. I shot the bear twice with my .375 H&H. My bear load was a 270gr TSX bullet over a stiff charge of RL-15.
The first shot was a pass-through on both shoulders, which put the animal down. It got back up on its hind legs and thrashed around a bit, biting at its shoulder. I put a second shot into it, to anchor it to the river bank - no chasing brown bears in the dense brush for me, thank you very much!
For the second shot, the bear was on its side, facing away from me. The bullet entered behind a shoulder, near the spine. It broke several ribs on the way in, and paralleled the spine all the way to the base of the skull. The reacted to the second shot like it was hit by lightning. Lights out! The second TSX had traveled through about 3 feet of brown bear, punctured the skin to leave, but never exited. We found the bullet when skinning the animal; it just popped out and fell in my lap. A perfect X-Bullet mushroom - just like the magazine ads. I weighed the bullet, once I got home, and it weighed 270 grains. Pretty tough to beat that kind of performance.
This was my first experience with Barnes bullets on game. With this kind of performance, though, I don't think it will be my last.
