I've used the the Warne QR mounts on my .416 Ruger for several years now. I have the old type, with the single screws, and they have worked well and come back to zero every time. The new ones look to be even stronger as they have two screws above and below. If you plan to hunt dangerous game with this rifle I suggest you do three things: 1)Install a GOOD recoil pad,ie. Decellerater or Limb Saver, 2)Order the nice 3/32" front site replacement from N.E.C.G. Runs about $18, 3)Install a low power(1-4.5X or similar) scope with QD rings (ie. Warne or Talley). I feel you will be getting the maximum benefit per dollar spent with these changes.
