I'm building a 20-22 inch packing weight 30 Nosler. Got the Peterson brass cheap, used Whidden's off a member here, and I have a fresh keg of N570 ready to go. Should end up sub 8.5 lbs scoped ready to go. The Nosler will allow me to reach the speeds I want to with less barrel than a win mag or PRC. The PRC is nothing more than a modernized 300 win, which is fine and if you're shooting factory ammo it absolutely trumps the Nosler. But push the freebore out, and stuff a 215 on top of a pile of N570, the Nosler will pull ahead. I feel Its a good happy medium between the win mag and the RUM.
