I hunted for a few years with the mildot version of that scope, and it accounted for several mulies, antelope, and elk. Overall, it was a very nice scope, but in the end a few things bothered me enough that I replaced it with a more hunting friendly scope.
The few things:
1. Length/weight - it was a big long scope.
2. Turret size - tough to get in and out of a scabbard (whether horse or Eberlestock).
3. Magnification - wanted a little lower low end, and the small exit pupil on the high end made head position and low light tough.
I ended up replacing it with a Swarovski Z3, which is an excellent hunting-friendly scope. The new VX-6 series from Leupold is also very nice. I really like the value that Vortex offers in their Viper/ Viper HS line of scopes. Sightron make the excellent 2 Big Sky Scopes. There are also other great scopes out there.
What is your budget and expected uses for this scope?
Species? Terrain? Foot or horseback? Range? Budget?
I was able to sell my Mark 4 for a good price second hand. They hold value very well.
