If you're shooting 6/6.5x47 then Id steer away from MDT 's mags. I had a 6.5x47 that I tried them on, and their internal "rib" that runs the center of the mag to help stabilize .308 and Creedmoor cartridges, sat right at the shoulder, and would cause any rounds over 2-3 to bind and get stuck. It would work if you could use a spacer to push them forward slightly, but for all the hassle, just get an AICS or Accurate Mag. They both work great with very little tweaking.
For .308 based cartridges though, I love my MDT Mags.
