Thanks Guys.
I went out Tuesday night, had a fox in my scope at about 150 meters, pulled the trigger and missed, this is the 2nd consecutive miss. So i spent a few hours zeroing to find i was miles out, 3inch left and 2inch low at 100 meters, obviously knocked it at some point, (mounts and rail secure).
only to then find out when travelling down from an old quarry when speaking to the farmers daughter, she had seen a big dark dog fox taking her chickens in broad daylight 3pm, while i was zeroing just half a mile away. (15 chickens are missing, i found feather in the cattle shed, seems
