Shawn,
I'm envious!!!. Please list some ballistics for the new "iron." Winchester felt that they couldn't get the best ballistics from the 338 WSM; hence, went to the 325 WSM. Not sure if that is just the "party" line from Winchester or what. I am in the process of building another XP in a 338 caliber, 338 Fed to 338 WSM. Let me know, my caliber decision may be based upon your results.
