I just had a custom turret installed on my rifle and had to send in the bare scope in to get it installed and after getting it back and put back on my rifle my point of impact has changed drastically, vertically it was 1/2" high at 50 yds to 8" high at 50 yds horizontally it stayed the same, that seems like a huge change and I was wondering if that could be expected or do I have something wrong with how I remounted the scope, thoughts?
