I'm considering building a 6.5 saum on one of my Winchester wsm short actions. At this point what will sway the decision one way or the other is what I can achieve velocity wise with a 6.5 160gr matrix vld. I can run out to a 3.04 col. in the mag and that puts the base at the shoulder/body junction. It will be a hunting rifle so I will run it hot. 26" 8 twist 5r. What can I realistically expect to generate ?
