I run a Burris 2.5-7 and after 800 rounds on my 8.275" 460 with no problems. It's handled everything from 45 Long Colt equivalent 255 grain bullets at 900 FPS (Trail Boss is our friend!) to 335 grain hard cast at 1725 FPS. Remember when you're shooting this beast, you can't "manage" the recoil, but you can ride it out.
