Vortex Crossfire Problem

[Varner]

I have a Vortex Crossfire scope, 6-24x50 AO, mounted to a Remington 700 SPS Tactical in .308. I noticed today at the range that after I zeroed it, shot some groups, that the elevation turret jumps...as much as 3-5 clicks over the course of a few rounds...checked it, re-set it, and it did it again....not as much on the windage, but def. the elevation. Is the scope broken, or is there a way to fix this, or is this somewhat normal? I wouldn't think this is normal, but don't have a lot of experience with scopes. I contacted Vortex to see what they say as well....thoughts?
