Okay I have a Nikon Primos which I really like for the last two years.  I am trying out another scope at this moment.
 
I am having an issue (but could just be me and the new scope).
After adjusting what I believe is my cheek meld and the eye relief, I notice that I must be so very perfectly and exactly behind the optics. If i move slightly to any direction I get a slight gray blurr on that side.  Is that the scope or have I just not noticed it before on my 3-9x40.  This scope is a 4-16x40mm. Both use the same rings so it is the same height.
 
Thanks
Steve

might be a lack of relief on the new scope?

^^ Isn't this what they call the 'Eye Box' or the area where the eye relief is at the optimum?

It sounds like it might be eye relief. have you tried moving the scope back and forth in the rings to see if it changes what you are experiencing?

As posted above, I am confident you are referring to the "eye box" .  This is an area behind the eye piece that is three dimensional, it has a side to side dimension, a top to bottom dimension, and a depth dimension.  When your eye is placed within the box you typically have a good view through the scope.  A small eye box is pretty hard to use and a large eye box is pretty easy to use.  I don't think you can deduce the size of the eye box from the scope specifications.  In my experience  higher quality, or at least good quality, scopes usually have a bigger eye box and less quality ones have a smaller eye box.  The depth dimension can be adjusted by placing the scope either further forward or back in the rings.  The other two dimensions may be adjusted to a degree by using the proper height rings.  This all helps if the rifle fits you well too.

Excellent answer and I believe you to be 100% correct. The "other scope" is a very inexpensive scope. I am testing the inexpesnive scope out.
 
Thanks all
Steve

In case anyone wants to read my experience with this "inexpensive scope", I posted a response under " Cheap illuminated mil-dot".

It was fun and I learned another thing in life.

Some things you can go cheap and get away with it, and other things you can't.
