I just eyeball the Ocular lens over the ejection port and then seat it in the mount groove closest...

 

Mount it to your scope eye relief and try and get a low to med. ring so you do not have to get your face off the comb. I like the Weaver Grand Slam Steel Lever Lock rings in the high set as they will put your scope eye bell almost right on the rail. And they are all steel and only $29.99 at Fleet Farm. Pete

 

As long as you can see through it, distance won't matter. It just depends on your preference, the scout scopes generally have a range of eye relief.

 

You do have a range of eye relief but not that much. You will Know when you have it set at the right distance. It is the same as mounting any other scope. If it is too far away or too close, you will not get the full field of view.

 

You dont want it to close or else you will get smacked with the recoil.

 

If you get it close enough to get smacked by it then you would not be able to see through it anyway so you don't have to worry about that and that is one reason the scout setup is so popular on the 45-70 and other heavy recoiling rifles.

 

Thanks guys!

 

True Scout Scopes, aka "Intermediate Eye Relief Scopes" will have an average eye relief of ten to twelve inches.

 

Mine's as far forward as I can get it on the XS Scout Mount, about a foot or so.............

 

I mounted mine as low as possible, can just get a sheet of paper between the mount and scope bell. Gotta mount it so that the eye relief is right, not for looks. Dont waste you money on Burris QR rings. They only have a corner of the ring that engages the weaver slots... A 45/70 will destroy them in no time!
