Yeah, I zero'ed it on an indoor rage, then shot with the same lot/box outdoors. So, yes there was a POI shift, which I adjusted for and the group were great. I then switched to a new box/lot. The groups were still great... Just 2" high from where I was with the old box/lot. Like I said before... I get the fact that there would be a shift, just wasn't expecting a 2 MOA shift.
