The plumb line at Pete's farm
Last Tuesday I paid my weekly visit to the farm to check my aimpoints and do some plinking. First things first: level the scope. Drop the plumb line, attach the level to the dovetail, turn the mag on the scope down, get everything lined up.
Sort my aimpoints, everything's looking good at the far end, pulling a little bit right at 8&10 yards, but still workable.
Gun back in the bag, back up the M11 to home, putting the gun back in the safe, what's this? The scope is visibly canted.
It's not the first time this has happened, I'm wondering if anyone else has had this problem? Is there some kind of local gravitational distortion?
