My go to, have to get it done, total confidence rig is a .300 WBY that Karl at Kampfeld Customs built. It's setup with a 26" fluted #3 Bartlein, McMillan Hunter (Sako), and Swaro Z5 3-18 with custom dial, in Talley lwts and is a drill with WBY 180 NABs.

If I can ever post pics again, I will start with it.
