I did have a Bushnell Banner on a Ruger No 1 in 416 Remington Mag for several years. It was a stright 6X I sold the rifle but that scope is still in use now on my 260 Remington. A friend of mine has a Simmons Aetec on his 458 Win Mag and its made several trips to Africa. Most all companies make some good and not so good scopes. I would put the Aetec up against anything short of a Night Force or Shepard. The Aetec is good for the big Magnums because it has 5 inches of eye relief. Midway sells them fior 139.00. I just ordered one for my Marlin 45-70.
