Re: How much eye relief is enough?
The general rule of thumb is the higher the magnification on the scope the less eye relief, but some brands do offer longer eye relief.
You may have had a perfect fit on your rifles, stock weld wise, so that you had a perfect picture once shouldered. Move your eye back and forth until you get no black around the edge, it may be that is has extra eye relief. If this is the case you may just have to shift your scope so it is spot on (perfect sight picture) when put to your shoulder.
Just remember if you shoot prone with the nightforce make sure you adjust the sight picture for that type of shooting. Also, some food for thought, you will see no black in your sight picture if the scope is mounted too close.... recipe for disaster (weatherby eyebrows!).
Nightforce scopes, such as the 5.5 - 22 NXS have a whopping four inches of eye relief!! Their scopes are intended for handling the higher recoiling rifles such as the .50 BMG, not a problem for the lighter stuff though. You just may have to mount it a little further forward.
Hope this is helpful.
