I have been using the Nightforce NXS 3.5-15 x50 with Mil-dot reticle for my hunting and it is a superb scope. Has an effective, easily operated illuminated reticle for poor light conditions (simply pull the third turret outward 1/8" or so for "on", push back in for "off"). The entire reticle lights up red, not just the center. NXS turrets are very good - lots of adjustment lattitude, very crisp and completely reliable.
If you want more power range the 5.5-22 x 56 is also a great scope, getting a little big compared to the 3.5-15 but optics are superb, same illumination, great performance. I believe that Len uses one of these on a favored LR hunting rifle. I use mine for target shooting on a heavy rifle. Not sure what NXS would cost in pounds, the NXS's go for about 1200.00 U.S I believe. Check www.nightforcescopes.com.
Nikon is about to come out with a 4-14 x 50 tactical with illuminated reticle option and it is a super sharp scope, nice size for hunting. Illumination dial gives you choice of red or green in varying intensities. Leupold also has a good one in that power range, not sure about illuminated reticle. These are all 30mm scope tubes.
Darryl uses 8-25 Leupolds quite a bit I believe, perhaps he can provide info on that model as I haven't shot it.
The deal is that you require a scope with the reticle in the second focal plane - American style - so that the reticle remains a constant size for long range shooting. European first plane reticles increase in size with the power zoom - as the object increases in size so does the crosshair - makes for difficult holding unless the reticle is very fine. Most European reticles are the opposite - big and bold for low light shooting I believe.
Good luck finding what you require.
