I've killed a whole lot of Plains game (and seen killed with the same rifle used by others) with a Mod 700 classic 300WM and the older Barnes 180xbt. I see no need at all to use a 200gr in a 300WSM. In fact, the 168TTSX will do everything you could want of your 300WSM! But...if I used a 200, I'd use the Partition so as to get all the powder room I could. But no kiddin...try that 168TTSX! smile
