I actually rezero'd my rifle during the first 3 stages which is why my scores were so low. Cold bore stage I was .3 mils high and left. Made the adjustment and came back to the 100yds stage and was .2 right. Threw it on the dial and ran the rest of the match.

My POI was changed with the following adjustments:
1. new buttstock
2. Extended LOP from 14.5 to 15.25" (Forgot to re-measure after installing a new folding adapter before the last range trip... DOH!)
3. New rear bag.

All these together changed the recoil characteristics enough to throw my zero off, but if you keep your head on straight, take notes, and make your adjustments it can still be a good day in the end.
