Sighting, how far from a scope should your eye be?

[angrybear]

Wow you like to make things difficult dont you

All you need do is put the clamps on the rail in nominal positions and then mount the scope. Do up the top halves so the scope can slide in the mounts with a little friction to hold it in place.

Then you mount the rifle with your eyes shut and adjust the scope back and forth until the image is right repeating the closed eye mount proceedure.

Tighten up the front or rear mount to hold the scope in place and loosen and move the opposite mount on the rail for its final position say to allow for a lamp mount to be fitted or to avoid saddle/mag clash.

Tighten the adjusted mount then do the same with the last mount if requroed.

The other important question you need to consider is what height mounts yo go for - low med or high. The front objective is a consideration here as big diameter scopes may need med or high rings to clear the action/barrel and the mag projection needs to be considered too along with saddle clash.

If the scope is too high, you encounter the floating cheek problem so whilst the scope is on the right eye releif position, your eye is below or above (and in some cases) left or right of the perfect eye alignment.

In reality, an adustable cheekpeice is the only way to correctly set up your rifle but most stocks do not include this as std. An adjustable butt plate to tweak height and angle of contact with the shoulder is also a big aid too otherwise your like a quaver - "floaty sight".......

The whole length of your explanation & the number of issues covered is exactly the point I was trying to make about being able to consentrate on the correct sight picture alone & not being distracted by other aspects of rifle fit not connected to eye relief,
seems you kind of missed the point.

Hi,

It sounds like your stock may be a bit low, certainly it's worth eliminating this possibility. There are commercial products to address this:

But before spending any money, try padding the stock up with whatever you've got to hand - foam rubber, folded cloth or whatever, held on with a couple of elastic bands - start thin & work up to see if there's any improvement?

Also, you say "I found that moving back a bit gives a clearer view but with a bit less tolerance of lateral movement." I think that will be the correct eye relief for your rig.

Approximently 2.5 tp 3 inch i would think !

No I didnt

But try holding a ruler with the rifle and the scope to get it right.

You dont even need to know what the eye relief is. Yoou will find out what it is when the scope is on the rifle and you can get level.

The method I described allows you to get it right to the millimeter without the risk to your eyeball

I mentioned the other stuff because it may be factors others will come across when they come to do the same things so stuff like height of mount or the necessity for reach forwards might be predicted rather than buy the wrong kit and have to wait before you get the right solution.

It is bourne from having already been in the position myself and getting frustrated when you have bought the wrong stuff or the mounts too low or....

But each to their own
