My dad has a Leupold VXIII 6.5-20X50LR on his 6.5WM Sendero. A few weeks ago it suddenly started making on half adjustments on the vertical. For example, a 3MOA adjustment only moved point of impact 3" at 200 yards. This is a 1/2 MOA gun. We could recreate the error over and over again. We sent the scope back to Leupold with a very detailed description. After three weeks they sent it back with a note saying nothing was wrong with the scope. Dad called them and they insisted that it had been thoroughly checked and "everything is fine." Today I remounted the scope, locked the gun down and did a grid test. I only ran a vertical test due to time restraints. MOA on scope \ Crosshair movement at 100 yards 0 \ 0 2 \ 2 4 \ 4.3 6 \ 6.75 8 \ 9 10 \ 11 12 \ 13 14 \ 15 15 \ 16.2 Return to zero \ Zero returned perfectly -2 \ -2.2 -4 \ -4.5 -6 \ -7 -8 \ -9.0 -10 \ -11.5 -12 \ -13.8 -14 \ -16 -15 \ -17.0 I did this test twice and it repeated exactly the same. The decimal values are simply a visual estimate based on the grid. Before we call Leupold back I want more opinions, being new to LRH. Is this the best you can expect from this scope? Seems pretty bad to me. /ubbthreads/images/graemlins/mad.gif Thanks for your thoughts.
