Re: Need advise on extreme range scope...
I just installed a 3.8-22x SN3 on my 338LM and the eye relief is fine, at no time during firing the rifle did the scope come close to hitting me, I even wore my glasses which reduces eye relief another .25-.5 inches.
No matter what scope you get then you will want a 40 MOA tapered base, before this SN3 I had a 5-22x NXS and both of these scopes needed a 40 minute base. As far at the SN3 making it out to 2000 yards. I have the 90 click BDC knob on mine and it has enough elevation adjustment to go from 100-1850 yards, so I could not make it out to 2000 yards by dialing in but I did get USoptics new MOA reticle which gives me another 40 minutes of holdover adjustment so I could shoot past 2000 yards no problem with this setup.
The SN9 is a great scope it is just to big and sits up too high on the rifle for my taste.
I'll post a picture of the scope mounted on my 338LM in a while.
