I just bought my first scope for my 10/22 yesterday. It is a BSA 3-9x40 at BassPro in Foxborough. They mounted and bore sighted it for free.

So I bring it to the range today, setup and start trying to sight it in at 50 yrds. I adjust for elevation and windage, as I've read and seen on various youtube videos, and things start to look pretty good. I'm getting nice grouping very close to center target.
However, after about 25 rounds I notice the crosshairs are not vertical any more. After another 10 shots the crosshairs are now totally diagonal in my scope. The scope housing itself does not appear to have moved at all. Shots still appear to hit close to center target and it looks to me that the crosshairs are literally spinning fractionally counter-clockwise with each recoil.
I'm fairly new to scopes but even I can tell something is totally F***ed up here. I plan on returning this scope tomorrow assuming it is defective. Has anyone seen or heard of this before?
