I'd have target turrets put on the Zeiss with a Kenton Industries turret matched to your load. You can have Zeiss put the turrets on, or I believe that Kenton will do it as well. Check lead time and pricing from each.
Having said that, I sighted in my 340 Wby with the same scope as yours at 250 yards last fall. That puts you with a dead elk out to 300 yards and based on previous hunts I thought I'd probably be fine.
Of course, my only shot was at 400-450 yards. I pulled out my trusty iPhone, inputted the range into the Shooter program, unscrewed the regular cap from the dial and dialed up the right number of clicks for the shot. Got my elk, too.
I will not do that next time, though. I've already purchased another Zeiss with target turrets for my 340 so that I don't have to wonder if I dialed the little adjuster the correct number of clicks.
What outfitter are you using?
