For those of you not used to hunting ahorseback, check your zero on your rifle after a few days of carrying a rifle in a scabbard.
Unless you have a quality gun, scope, mounts, and are a real American hunter, rather than a true POS Muzzie lover.
I've had a rifle change zero after being in a scabbard; no scope or mounts involved. An open sighted rifle with a rear sight that had a spring under it. You turned the screw up or down to change the height. Spring kept the sight up against the screw. The scabbard pushed the sight down and the screw turned out (because it was now unloaded) due to the jostling from the horse. Missed a four point bull at 80 yards because of that; shot right over his back. These types of rear sights show up on a lot of guns, best thing to do is locktite them, but it can make changing the zero a bitch, depending on how much glue one puts in there.
You see in this world, there's two kinds of people my friend; those with loaded guns, and those who dig. You dig.
