Get a call yesterday from a pard. Checking zero on dad's rifle. Its off 5" to the RIGHT and 3" HIGH, though it did shoot a 1" group at that location. (I think to myself, how the hell was it off that much). I adjusted 20 clicks left and 12 down. Now its grouping 6" LEFT and 5" LOW.

Leupold, I asked.

Yes, VX III, what should we do?

Throw it in the trash and buy a NF (which is literally what I would do).
