Welcome marlin45. One of the Big Bore shooters will be along no doubt to help with your request.

I had a problem adjusting the Warne QD rings on my 9.3x62. Definantly operator error on my part but I beleive if adjusted correctly they should be fine. The straight tubed scopes, as you seem to already realise, are de-rigeur on these rifles.

High magnification may lead to loss of the sight picture under recoil.
