I'm trying to wrap my head around POI shift and need some references to read up.
Shooting a new to me 30-06 featherweight model 70 yesterday which seems to group fairly nicely.
Started with some 125gn loads that were proving to be particularly accurate, then jumped all the way to 180gn. Noticed that the 180gn were still grouping nicely, but the POI had shifted to the right by 4-4.5 inches at 100m... that seems absurd. Shooting both off bipods. No rear bag.
