The Conquest Z800 is recommended for the 270 WSM and 7 mm R. M. This is what was printed in the manual when I picked my Z600 for my 7 mm R.M. Now I thought I was in a pickle being that I had the wrong reticle after purchasing my scope. I contacted Zeiss and they had suggested on going on line to verify the reticle with the velocity of the rifle. I would suggest to check it out for your self before purchasing your scope, just in case. As for the scope, I like what I see so far, although I haven't used it yet. Good luck...
