I apologize for getting your gender wrong, my assumption was in poor taste. However, I maintain the point that I made. Zeroing a rifle and then trashing through the mountains for a week and having a poi shift is a **** far site from evidence of a scope malfunction. In my experience, you are about a hundred times more likely to have moment in your rings or bases, or more specifically the screws that hold them together than the actual scope. You'd have to do some box testing or some test shooting before you could determine that the fault lies with the scope itself. What will you do when Leupold returns it and tells you that there is nothing wrong with the optic? Trash their customer service and sell it swearing to never purchase from them again? Now, if you re-zero the optic with all of your components torqued and while firing it begins to walk, then you might have an argument. It could be an ammunition problem. Some lots of factory ammunition can cause a poi shift as far as you've had. There are a dozen things that could have caused your problem. A muzzle brake could have spun loose a half turn. I have been playing this game all of my life, and I have seen way too much of this to believe the scope just decided to move on it's own, and you don't seem to have done nearly enough testing to be bashing the company. But hell, I could be wrong, it wouldn't be the first time. I just wanted to know how you eliminated the other dozens of variables before you decided the problem was definitely in the scope. I've also seen people zero their rifle with a warm bore, and then their cold bore shots (in rare cases) will have a significant shift in poi. I apologize for being insulting, but I was really intrigued by your issue, as I own dozens of leupold optics including binos and spotters, and I've used them religiously for decades without any real issues, so if your issue is authentic, I want to know. Thank you
