Re: Zeiss or Sightron? Feedback
What scope do you have on the 7 mm Dakota? You must have a reason for wanting such a high mag range. Personally, I would go lower, say 4.5-14X. Thats just in case a something walks out in front of me at 30 yds and I have one second to acquire, aim and fire. Glare performance and brightness at duskl/dawn are both better for lower mag scopes.
That said, here's what I have on Sightron: All the variable magnification SII and SIII scopes I saw at SHOT had below average to average glare performance. I specifically looked at the 6-24X50 because I wanted to see if the glare performance had improved since last year (not so). For a range scope, that's fine, but not for hunting scope. I recommend you look elsewhere.
I have not visually inspected the Zeiss 6.5-24X50, so I can't say for sure. However, all the other Conquest scopes I have evaluated had above average glare performance. I have no concern about glare performance in the Conquest line.
Incidentally, the Burris XTR 4-16X50 has good glare performance and good correction of off-axis aberrations. All the Weaver Super Slam and Tactical scopes I've inspected had good optical perofrmance. Something to think about.
Lastly, what are you using for a ballistics computer? I use an iphone with Ballistic app and it gives vertical/horizontal holdoffs in moa/moa, moa/mil, mil,moa or mil/mil. For me, it would be not problem using a moa/mil scope if I had to. I would just train with it to make sure I was solid on dialing moa for elevation and holding off mils for wind. I'm really nudging you to reconsider a Leupold. VX-3 scope have generally average to good glare performance. Mark 4's are good, period.
