I saw a lot of failures of the original Barnes X bullets on whitetails from guys in my hunting camp that used them. I got to trail more than a couple of wounded deer because of what I think was their failure to open. Because of that I developed quite a dislike of the X bullets. Fast forward about 20 years and now I'm a confirmed TTSX/LRX slut, they're almost all I use now. I think the plastic tip makes all the difference, it gives something to initiate expansion instead of relying on hydraulic pressure to open the hollow point. I've never seen a failure of a TTSX or a LRX unless you consider shedding a petal a failure, which I don't.
I still won't use the TSX because of the hollow point, but I don't see any reason to use them when the TTSX is out there. I also won't use other hollow point bullets like Bergers or Lapua Scenars on game, I just don't trust any hollow point to open consistently enough for my satisfaction.
