I have two high end(3000$ plus) scopes from the same manufacturer, same model, different reticles. I have been shooting out to 1730 yards and noticed that i was off about a mil on elevation. I chalked it up to my magnetospeed being off, and used my ab kestrel and did a mv calibration test at 1600 yards. My magnetospeed showed 2840 fps, single digit es, and the mv calibration showed me at 2940 fps. It is a custom 338 lapua, but standard chamber and 29" barrel, so i really doubted that number, but my drops were working out so i just rocked on. I got a random idea to box test them this morning in my back yard at 100 yards, with a long 2x6 i had around. I zeroed at 100, and then dialed up 15.5 mils, which should have been 55.8 inches. shot and my bullet impacted at 59.7 inches, over a mil high. Both scopes, different gun and different calibers, both hit at 59.7 to 59.8 inches difference, so it wasnt just one. I dont have any other brands to compare it to, but will ask yalls opinion. Personally, i expected it to be off no more than half an inch for this test. Am i expecting too much? What do your scopes hold as far as tracking tolerance? Should i send them in and have them fixed, or just adjust my click values in my ballistics program and rock on? And before anyone asks, i am not going to tell which scopes they were, because this forum is too big, and google picks up way too much in search results, and the company deserves the right to fix the problem and address others concerns if warranted. So, what does the hide say? Thank you, Greg
