I am the only one or does anyone else have to adjust their scope 4 or 5 clicks up or down, left or right, after it sits for a week or so?

Depends on the gun, some brands are prone to barrel movement when bumped or leaned in a corner
. They lack a solid connection to the receiver

My spring guns, Ruger air hawk 177, Crosman nitro fire 22, 2 Benjamin NP Trails XLs both 22, Umarex Octane 22 caliber. I'll have them all dead-on at 20 yards (less than 1 inch group), but when put them down for a week in HARD cases, and I pull them back out I'm an inch and a half left or right up or down

I was noticing this phenomenon in my sig Sauer asp20 with vortex diamondback. It doesn't change alot, but overnight sometimes it will shift poi. Additionally temperature seems to affect poi as well. Frustrating.

I only have break-barrels but I have noticed this as well. I think it is a temperature thing between my climate-controlled home and taking them out in the elements with varying temperature. Most of my POI shifts are vertical. But my background reminds me that it doesn't take much temp difference for steel and plastic to expand, contract, etc.

Very interesting. My biggest change in poi is also vertical. Sometimes SLIGHTLY horizontal, but at large it shifts UP.
