In case anyone is still curious, I went back to the range the week before last to retest the scope, having scrubbed the barrel to bare steel. After 1 fouling shot, the rifle grouped well, and the scope tracked perfectly around the box.
I will, indeed, be moving it to the 722 (.300 Savage) as my go-to hog hunting rig.
The reticle and the glass make this one a winner for me.
