I've killed somewhere around 30-40 animals with the Barnes TTSX here in the US and also in Namibia. I've only recovered one bullet and that was a 180gr TTSX from a .300 Wby on an eland at 200 yards. The bullet went though the shoulder, the heart, a rib, and was recovered under the hide on the far side. Perfect expansion. The bull went about 20 yards. I lost one waterbuck along the way and have no idea to this day what happened. We all saw the bullet impact the shoulder. Everything else just died. No failures. No drama or long tracking jobs except one gemsbok that I didn't hit well the first time. Very little meat damage too, even when you hit bone. They work as advertised and I've used TTSX from .243 up to .340 Wby and TSX in .375 and .416 Rigby. Still waiting for a chance to try those out on actual critters.
For true long range stuff, I'm more inclined to go with Berger due to concerns about expansion at low velocity. That said, the .257 Wby and 100gr TTSX out to 500 yards is a perfect marriage in my book.
