Any scope can fail to hold zero-- that what it sounds like.


12" is hard to believe for lack of a fouling shot, but I always hunt with a fouled barrel.

Out of my Encore, first shot from a clean barrel is 4-6" high at 100 yards, then sub-1" .

Out of my Knight, first shot is 3-6" LOW, then groups sub-1" at 100 yards.

For 50 yard shots, I' d shoot with the iron sights-- and get the scope ?????? out of the picture. If the groups don' t dance with iron-- you know it is scope or mounts.
