I finally finished my 300 ultra mag build. Here it is

I used a savage ultra mag action, sss recoil lug, 28 inch sin arms barrel magnum contour, muzzle brake built by Al Story at Borchardt Rifle co, B&C duramaxx stock glass bedded. Topped with a 4.5-14 x40 leupold vx-3 cds, egw base and leupold prw rings. Thanks for all the info gained on this site.
