Never holds zero - Zeiss Terra 3x 4-12x50mm Rifle Scope

I put this scope on a .308 when I first got it, torqued it down and never could seem to get on zero, every group would love all over the target, so I tried everything, checked the torque, changed mounts, changed ammo, nothing worked, changed the scope to cheapie I had in the closet, and what would you know! Perfect groups. So I put it on another gun and the same thing, wondering zero. So I sent it back to ziess for warranty, and they told me there’s nothing wrong with it and charged me $65 to get it back. Definitely do not recommend this piece of garbage to anyone.
