For pronghorn hunting, actually all my hunting, I am. FFP guy. Accurate wind holds on any magnification you choose are a must for me. I have rarely had a calm day out in pronghorn country. And mirage is always raging when temps swing from 55° to 105° So being able to dial down and still have consistent holds without math problems is a must. Our last five pronghorn have been at 173 on 5x (5-25×56), 391 on 12x (3-20×50), 460 on 7x (3-15×50), 250ish on 4x (3-20×50), and 331 on 8x (4-20×50).
For $2k, I would look at the NF NX8 2.5-20×50 or 4-32×50. While the glass is not quite on par with the ATACR line, I like the lower end magnification availability. Having 2.5 to 4x is nice. The AMG would be a good choice, but 6x on the low end is too high in my opinion. I am quick at target acquisition, but just returned from an elk hunt where a 6.5-20x50 would have been much better if it were a 3-15 or so. That narrow FOV of the 6.5x minimum cost us two different opportunities on good bulls (a 300ish 6x6 @ 250 & a 300+ 5x5 @ 150 yards) when the hunter couldn't locate the bulls in the scope before they started walking away.
