Well I recently had a thread started about this same scope and rifle.

I have an Sightron S111 mounted on a Browning Xbolt SS 7 mm.

I had to Goose neck my head forward,to get the full eye box.
This ,with the scope mounted as far back as possible.

So on advice from others,I've ordered a one piece mount.

But ,what I didn't mention,because I only found out today,is that, this only happens on max power,24x.

When I dial it back to 9,12,14 power , I get a proper cheekweld,no goosenecking.

Oh,today was the first time I tryed less than 24 power.

I know,I know, I'm a dumbazz:)

One question remains though,
Is it normal for the eye box to change so much? When increasing magnification?

If so, How do you compensate for this? Or do you just do the Goose neck,when you increase your magnification?

Thanks again
 
"some" scopes do have changing eye relief. When mounting the scope, I do it on max power to avoid this problem.

more experienced members might have different views/methods.
 
My answer, yes the eye relief will change through the different magnification levels. How much and where depends entirely on the scope.

When I purchase optics, I try to get ones with the longest eye relief. 4" seem to work the best for me. The 3" ones do have tight eye boxes.
 
This scope ha about 4 1/4 eye relief.
Dial it up to 24 X and I get about 3 1/4 eye relief.

Nothing you can do about that ,other than stretching your neck ahead when on max power or moving the rings back and forth, on the mount. Lol
 
Adjust the scope position so it is right at the highest power. Although the eye relief changes as the power is lowered, at the same time it also matters less so the problem fixes itself.

Since you basically figured that out for yourself you might not be a total dumbazz. Others prefer to whine for the rest of their lives.
 
That's what I figured, I gotta find a happy medium.

I use the scope for load development,that's why I like the 24x.

But I want to use it for Moose hunting as well,
In which case,I'll more than likely need the 6 x.
 
All variable power scopes do this to a certain extent. The larger the range of magnification, the more noticable it is. If you look on the spec sheet of most scopes where it says eye relief, usually right under the magnification, it will normally list 2 numbers: one for the lowest magnification, and one for the highest.

You can use this to try and find a happy medium, or has been mentioned, set it up at the highest magnification, and as you go lower it is more forgiving and matters less.
