[QUOTE="Big Turnips, post: 2045599, member: 116408"] I shot silhouette both handgun and rifle. Every single range has its own set of sighting adjustments. A slight difference in angle of shooting affects the sights adjustments. Elevation affects adjustments, temperature, humidity and altitude do as well. The only thing I can think of for one of the rifles, the one you adjusted for your friend, not all of them...Is that if adjusted in humid weather, it shoots flatter. At high altitude or at altitude, (7200 feet is quite moderate) the air isn't as humid as at sea level or 850 feet. Humidity is air less dense and allows a bullet to fly with less drop. Dry air is more dense and creates more drop, although at altitude, rifles shoot flatter in general. Regardless, you will not see 2 inches of difference at 100 yards however. We each pull the trigger differently. You adjust a rifle (scoped or otherwise) for someone else, you've only adjusted it for yourself and no one else. I don't mean to be critical since we all at one time or another could do something similar for a friend, my point is that as has already been mentioned by others in this thread, there are too many variables in exterior factors and differences between one shooter and another.
