Barnes TSX Performance Issues
I had an interesting "failure" with the 180 gr. Barnes Triple Shock (TSX) at a lower speed.
I was shooting at a whitetail deer, 250 yards distant, with a .30-06. The TSX was loaded to 3740 fps muzzle vel, a calculated 2330 fps on impact at that distance, and has proven an extremely accurate load on paper. The shot was broadside. Entry was a little higher than point of aim (I had estimated range a bit more than 250), right behind the right front leg. The buck went down at the shot.
Here's where it gets interesting...
The bullet entered between two ribs, no expansion evident. It angled up and back, hitting the spine very clearly. It seems it then deflected hard left, parallel to the spine, and exited right above the anus. Exit wound seemed somewhat expanded, but it was hard to tell in the soft tissue. I found no evidence of any injury to internal organs.
The initial assumption is that the velocity was too low for full expansion or penetration, that the bullet deflected almost 90 degrees, instead of the expected penetration.
I've since heard anecdotal accounts of similar performance for TSX's at less than WinMag velocities, but nothing credible.
Thoughts or reactions, anyone?
