[QUOTE="davewilson, post: 454804, member: 4491"] I read a lot of posts that claim their scopes track great. i'm asking what everyone does to actually confirm this. i havn't seen this with many scopes. i'm not much of a believer that you can run a box test shooting 5 bullets and because the last shot went somewhere close to the first, it tracks great. since verticle movement of the POI is what we're mainly concerned with, i shoot 2 groups cranking the turret 20 moa in between each shot. this can also confirm it's ability to return to zero, if it's tracking the distance it's supposed to, if it's tracking vertically, and of course if it repeats. yesterday i did this with a Viper 6-20 and it didn't exactly pass with flying colors. the gun i used will rarely shoot over 3/4 at 100, 1" is about the largest group it will shoot. the upper group, the 20 moa high group was a bit over 2" and the distance the 2 groups were apart was about 23". my calculations tell me the groups should be about 21" apart so we're not moving the amount we should. in round numbers, this would put us about 20" high at 1k. i have one Luppy that tracks very well, of course i had to have it "Tuckerized" to accomplish this, and a Sightron. other than that, every scope i've tested, that i own, won't track very well. would love to hear from those with the new vx3's and PST's if they've actually given their scope an indepth test to confirm how well it "tracks" i don't need to hear from the Nightforce owners, we all know their tracking/repeatability is one of the features that makes them a great scope!
