Ive googled quite a bit and done the search on this site and several others. Ive only read good things about pretty much all of the vortex offerings but Im really curious about the tracking on this particular model. From what Ive learned you really do need to spend 1000 plus to get a good tracking scope. So has anyone really put one of these through a good test of repeated adjustments from various ranges? Im looking to sign up for a 2 day sniper course that does a lot of reticle based range estimation so return to zero and true clicks is an absolute must.
