I don't know if there are varieties of movement, it's all to do with scope internal mechanicals, tolerances and assembly quality. There's a lot of stuff going on in a small space in a high mag variable scope, most of which I have no clue about. I just know the problem can exist, in some scopes.

Give it a go, if yours does it, it's a relatively easy task to establish at what mag it happens, then don't mag above that.......or, don't change mag

I doubt it will though. Most are pretty good.

Here it is, it wasn't a brick wall, but a collimator grid

And the link to the article. Now you know as much as me.....
Hi Barry,

I appreciate you taking the time out to provide some great information for me to follow up on. I'll put my rifle on a gun rest and check it out. Many thanks. Stu
