I had a Buckmaster and was not at all happy with it. The eye relief was very crititical. You can look at one in the store and maybe this would not be true for you. The Monark would certainly do the job for you as would the Simmons Aetec which is a tough scope with more eye relief than any other scope I have seen. Five inches of eye relief which would be handy on a powerful Magnum. I have had several Aetec scopes and they will stand up to all the recoil that you can hand them. Several Leupolds would do the job well. Good Luck.
