Well got a call from Vortex today from a tech checking my scope. Said he couldn't duplicate my problem. We talked for about 30 minutes, nice guy. My PST should be on it's way back. I was very thorough in my scope mounting and trouble shooting the issue. I remounted my NF NXS and the results were perfect as usual. I can't explain it.
When I remount the PST I'll be picky as usual. I'm down to grasping at straws like wondering if something like the scope finish allowed the scope to shift in the rings. I'll clean everything with alcohol before putting it back together. Any other off of the wall ideas. I already triple checked the usual stuff and like I said the rifle was solid with the NF mounted just like it has always been with the NF and previous PST I.
I would be happy to find and admit that it was all me.
I'd assume, you'd have enough experience to have adjusted your Parallax correctly?
