[QUOTE="Moman, post: 249969, member: 10494"] I set my scope height at 1.6" That should be pretty much on the money. My sight in at 200 was only about 1/4" high. The loads were chronographed with two units. But, there may be some flaw to this. I have an old Pact that shows 2890 fps, but this same load used to show 3000 fps. All components were the same, even the number of firings for the brass, same lot # of all other components. I used a friends Chrony and it showed 3016 fps. I thought 3000 would be very close to actual. When I validate for 675 yds, the velocity changes to 3044 fps. When I validate for 1000 yds, the velocity changes to 2887 fps. [/QUOTE]
