I burned through three full sessions chasing this before I actually found the problem and the whole time I was convinced it had to be something with my technique, since I hadn't changed ammo or done anything obvious that should've moved the zero. But it turns out there was a tiny gap in the battery compartment that I'd never noticed, just small enough that the battery was seating a little differently every single session without me having any idea it was happening.
Once I tightened the cap and re-zeroed, the problem disappeared completely, just like that. If your point of impact shifts and nothing about your ammo changed, it's usually hardware quietly doing something you haven't caught yet. It is worth working backward from the shift itself and tracking down whatever's actually loose, instead of assuming it's you.
Has a mechanical issue like this ever cost you way more time than it should have before you finally tracked it down?
