The 160 TTSX has impressed me the most. Very accurate, and kills very, very well. I probably wouldn't use the 180 BT on elk again. Not that it didn't work, but just does not penetrate like the Barnes. Broadside shot on elk from about 40-50 yards and the elk dropped straight down and I heard him thump on the ground. But he didn't seem to have the internal damage the TTSX has given. Not bad, just not as good.
I have harvested a bear and several whitetails with the 160ttsx and it is quite impressive. I have also harvested several whitetails with the 185 tsx and I would not hesitate to use either on any animal in North America inside 200. IME the 185 tsx is a better meat retrieval bullet but the 160 puts them down a little faster.
