Depends on the height difference between your bore and scope. But you should be around an inch high at 100 yards if we're talking an AR. I always zeroed my AR with an EOTech at 50 yards because it was close to being a 200 yard zero as well. Not sure why you'd zero it at 25?
Aimpoint's spec but I'm open to ideas. It's the Larue mount with a micro.
