Nice video. My wife has that same set up with a muzzle brake. We're shooting the 140 sst 1/2 inch groups. I want to change her over to the 150 Nosler LBR with the high BC she'll be able to shoot out to 800 yards. I wasn't to impress with the Berger bullets as far as shock and awh. The new Hornady XLT are the new rage out here. I've bought a box to later try out in my RUM. If your friend reloads the go to powder for the 270 WSM is MagPro.
