I suggest A Vortex 6-24x50mm PST FFP MOA with a custom turret. I am able to shoot out to 1,000 yds. and put 3 five shot groups into the boiler room of an antelope with my hunting rifle. The group sizes are in lower right of target. If you want more power and don't have it, OH WELL. The glass is very good and was good enough to see a 4 point whitetail at about 100 yds. more then a half hour after shooting time which is sunset . It was so dark I couldn't tell if it was a deer or dog with my eyes, but when I looked through the scope at 24x I could see the 4 points.
The turrets have been spot on even after turning them up and down hundreds of times.
