First shots and hand loads out of the new 783 243 @ 100yds. 105 Amax down the tube first. Total warm & fuzzy feeling with results. Then I shoot 100 HDY BTSP and Sierra 85gr and they hit 2-2.5 inches left. I’ve never experienced such a POI change on loads. Is this legit or something deeper and more sinister going on? The arrows are pointing to my point of aim.
