I'd be a bigger fan of Barnes if seconds that shot just as well as firsts were available for about half price (or even less sometimes), like the Noslers are from SPS.

I use the 150gr TSX in my 7-08 because it shoots better than the NPT's I've tried. Otherwise all my elk bullets are NPT 2nds. Given my observations/experience NPT's tend to be a little more consistent in their performance on elk than the monos, and when I can buy NPT's at roughly half the street price of other elk worthy bullets it's a no brainer.
