There's quite a few, that I know of. Nightforce, US Optics, and a few that I have seen in different custom shops (Kelbly sells a brand witha ridiculous magnification range, but they're pretty expensive). Shmidt and Bender, Hendsolt, Swarze, or Zeiss (pardon the spelling), Leupold, and even some of the Bushnell Elites are also quite helpful. For everything other than the bushnells and leupolds, you're looking at 2000-3000 dollars (other than a few Nightforce models). The leupolds will run between 1000 and 2500 for the long range models, and the elite 6500's capable of that are 2.5-16 and 4.5-30, between 850-1100 depending on where ou go. The Zeiss Diavari, the Kelbly scope (made in Japan ina custom shop), the higher range Hendsolts, US Optics with custom options, some Swarzofski's I'm sure and the Shmidt and Benders can weigh in well over 3 to 3 1/2 g's, with the diavari and Hendsolt coming in over 4. Hefty prices for glass, but if long range is your thing, indispensable.

You need zero parallax at that range. As you move your eye around behind the scope, the cross hair must stay right ON target so you can't mess up the shot with slightly differing cheek weld from shot to shot.

We all have our opinions but I would rank them Nightforce, then U.S. Optics, then Leupold. I expect the difference in accuracy to be about 1/4 inch at 1000 yards from the Nightforce to the Leupold. I actually use a VXIII 6.5-20x Leupold because saving $1000 there allowed me to spend more on a great long range barrel. I've shot 3.5" 1000 yard groups with that scope and it works pretty well. The barrel is going to give you more accuracy impact than the scope as long as you stay with one of these three manufactures.

Good luck on your long range shooting! I know it is a tough decision but any of these three is capable of putting you in the finals at 1000 yard competitions as long as you and your rifle can shoot!

Although what fng says is true if it got down to one scope I would have to have it built by US Optics. I will have to look into the Kelbly as it sounds very interesting.

Ish, the Kelbly ones SOUND great, but I haven't heard a tonne about them. I'll get the link and post it for you. Also, sorry for not posting; between university, weightlifting, hunting and the chasing of things fair fairer and more fickle than our lord the Whitetail, I've been rather busy.
