I have a NS8 1-8 and have hunted Africa with it on a 375. Maybe busy but when it was time to shoot, I centered it on target.
Nightforce scopes are bulletproof. This NX8 is however first focal plane with the reticle increasing in size as the power is increased. I do NOT like this. For 2023 NF offers a reticle with a smaller center dot. That would be better for shooting 100 yard cloverleaf's!
The NX8 has a illuminated dot and surrounding circle. Turn it on and a near blind man could center it in target.
Bottom line is that if this were second focal plane with a simple reticle, it would be golden for a dangerous game rifle.
I also own several NSX 1-4 which have rather simple reticles and are second focal plane. They are out of production and mine are not leaving my rifles!
Additionally, I compared the clarity of the NX8 1-8 to a Leupold VX5 2-10 gazing at a field 350+ yards away. It was the Leupold with it's 42mm objective lens by a mile!
I think the happy middle ground for a DGR would be the Leupold VX6 1-6.
