focal point in midrange (price) scopes

[wce323078]

I wonder if anyone can tell me by their own experience it is common or normal for the focal point to change when using the zoom on a 6x24x50 scope? I have a couple of Sightron[ 6x24x50 and a vortex viper PST and I find myself having to change my cheek weld when using the zoom. IE moving my head back and forth. I find it a pain in the neck.

And while I am writing this can some one tell me how to enable spell check?/B]

it common yes, as you zoom in the "eye box" and eye relief tend to get smaller and shorter, even with some high end scopes

The eye relief on most scopes does change. The problem is made worst by high ratio.
A 20 X 30 scope would have more constant eye relief than a 4 X 30.
Constant eye relief is very difficult to maintain, even on expensive scopes.

Make sure your occular lens is adjusted properly, that will help.
