Use the TTSX, run them light and fast, if broadside aim for the high shoulder 1/3 down from the back. If quartering, aim for the forward edge of the shoulder down 1/3 so it exits on the rear edge of the offside shoulder. If possible, wait until they lower their head. For some reason I cannot explain that does make a difference.
Do not aim for the lungs with any bullet as animals can run 50 yards or more easily with a lung shot. Where I hunt in thorn brush, a 50 yard run can mean an hour or more to crawl on the ground with the Texas earth worms to recover an animal. Anchor the critter and don’t worry about losing a pound of meat.
Hitting the high shoulder impacts the thoracic spine even if the bullets goes below it without contact. There is no “breaking down” doodly squat, it is the science of killing. The thoracic spine between the shoulder blades is like a master breaker switch. Impact that, the rear legs collapse with the rest of the body dropping straight down. A shot in the brain stem, not the head, but the brain stem, produces the same result if the rifle and driver nut are reliably capable.
fwiw - I am not a fan of TSX’s for deer and pigs and swore them and Barnes off long ago. Then about fifteen years ago, friend encouraged me to give the TTSX a try when they came out. I did and they have become my go to first choice. After hundreds of deer and pigs, the TTSX has provided uniformly consistent DRT results with the placement described above. With heart shots, they may make 30 - 50 yards. The same occurs with the handful of lung shots kids have made.
Use a lighter and faster TTSX for the cartridge compared to a lead bullet.
For .308 Win, I use a 130 @ 3100, a 150 at 2900, in .30-06 a 150 at 3,000, in .300 Win Mag the 165 @ 3100, and in .338 Lapua the 225 @ 3050
- 3100.
I have not used LRX’s enough to opine other than they are supposed to be softer to open at lower speeds. The TTSX are absolutely fine to 300 yards and much farther in the .338 Lapua.
Last, they typically do not make big exit holes because they remain intact, but they do tremendous damage and plow through and almost always exit. When they exit, even if they double in size, that means a 3/4” hole. If one wants a huge gaping exit hole, use a more frangible bullet, with the Partition being a unique combination of very frangible front end while the rear remains intact.
Here are a few videos taken with my wife and a nephew doing the shooting.
This is why I use Barnes TTSX’s and strive for DRT.
Here is .308 130 TTSX from a mature South Texas buck that was angled, not quite head on, at a nephew. The bullet was removed from the inside of the rear leg under the hide, more than 3 feet of penetration from a .308 Win and the little 130 grain TTSX.
Here is a wound from a .300 Win Mag with a 165 TTSX on a Scimitar Horned Oryx with an old school low behind the leg heart shot:
