Here are my zeros and holds using a 200 yard zero and a 340 yard zero using the cross hair and the duplex as aiming points on my Swarovski. This data maybe usefull to you if you shoot a 14.5 to 16 inch gun with a similar load like MK 262 or 75 grain Hornaday TAP. Bear in mind this only works on 6x and only with my load which is a 77 grain Sierra Match King going 2528. I turned the illumination off in the photo to better illustrate what I was talking about. You can make this work for you if you have more or less velocity by tweaking your zero range.
