I started using the 168gr TSX and probably will not HUNT with any other bullet under 400 yards in my .308s. I love their performance on game and I now have no need to try a Scirocco or an Accubond. (so, I have nothing to offer for comparasion)
But, if I know I am going out with shots greater than 300 yards, I would more than likely switch to my 30-378 and I will be loaded up with something else. I just don't like their BCs compared to SMKs or VLDs or even an AMax. The TSXs lower BC leaves less room for operator error. The tipped will be a little better, but still not as good as some other bullets out there.
Now, if they come out with a TTSX with a rebated base like the ULDs, that would be awesome. DO YOU HEAR CHRIS BARNES!!!
