Got some new Nosler brass so went to the range today to shoot a few groups and check velocity/POI of my go-to load developed in the new brass versus the Hornady I developed the load with. Shot 5 shots loaded in my old brass, which was dead center on the backer for windage. The problem is the group was ~19" below the point of aim versus where it was very consistently during my last range session. Pulled the bolt, set the rifle on the bag with the cross hairs centered on the target, looked down the bore and sure enough it was pointed at the very bottom of the target backer where the shots impacted. Re-zero'd the scope and shot 3 5-shot groups. All three groups were 2.5"+ which is considerably worse than the load was previously shooting.
Since the last range session I did shoot ~40 rounds on steel out to 600 yards which required a bit of dialing in and out. The rifle seemed to shoot fine during that outing.
The ring/base screws are tight, no adjustments/hard impacts since the last time I shot paper. Used the same bipod/rear bag as always when shooting groups. I am guessing this is a scope problem, but wanted input from more experienced guys as to whether there is something obvious.
