There is an extensive post about this very topic on another popular online forum. I am unsure of the rules here so I will leave it unnamed. However, Leupold optics are known to be problematic in this regard. I wont use Leupold on anything. Just heard too many negative experiences about them. People will say "Buy the Mk5", I'm sorry, it doesn't matter. Those are the ones that were tested in that other forum. Two of them. Both failed.
I now only have two brands of rifle scopes and only one of them goes on my serious hunting rifles, thats Trijicon. I'd be just as confident if they were Nightforce. Nightforce and Trijicon are the only two optic brands that I trust to hold their zero as of December 2024. I will use other scopes for local hunts near the house, or target shooting where I'm not out an animal of a lifetime that I hiked all day to get to and may be out thousands if not over ten thousand additional dollars in associated fees and expenses.
Something that people buying optics seem to struggle to fully grasp is the TRUE expense of when equipment fails. If you're on an outfitter backcountry elk hunt that you've got 10+ years worth or points, tags, guide fees, travel expenses, guide tip, etc all wrapped up and you take a shot and miss by a foot because your gun rode in a scabbard on a horse, or a side by side, or ATV, or you hiked it up a mountain in your pack that you set down every time to glass or have a snack or what have you. The rifle is getting jostled around no matter what your hunt mode of transportation is.
When all that is on the line, yeah man, you can keep your bullet proof warranty. I want a bullet proof product. Nightforce or Trijicon for me.
