If you are going to insist on high magnification variables, long eye relief is something you will have to learn to live without at the highest power settings! There may be some scopes that will give you a little more than the one you have now, but will it be enough?? I have used the Leupold 2.5-8X on a Ruger No. 1 in .45/70 that has a recoil level of 55 foot/pounds with one of my loads, and the scope has not hit me yet. But this rifle now has a Leupold Compact 4X on it, with a 4" + eye relief. (Incidentally, Leupolds are the ONLY make of scope I have tried on this gun which were not destroyed by its' recoil!!)

Keep yore powder dry!!
