Thoughts for the day; Barnes TTSXs, like Porsche, there are no substitutes Speed kills...
Jorge,
Actually, I have yet to be able to tell any difference in field performance between Barnes TTSX's, Nosler E-Tips, Hornady GMXs and even the old Fail Safe. I have been able to document slight slight differences in penetration and expansion when they're fired into various kinds of test media, but as far as on-game performance they've all acted remarkably simillarly.
