Well, whatever it was, I got over it today. Shot the lighter loads at 35 yards, and had 3 touching, and the other 2 within 1.5" or so. Bumped up to the hot loads, and shot an acceptable group. Decided to do it again just to make sure I still could, and sure enough, shot just fine.

Bring on hunting season before I forget how I did this!!
