I have the NF NX8. Love it. It's tiny compared to most other scopes in this power range.
I've had it out to 500 yards. I dial for elevation past 300, so the reticle is fine for me. I was worried the dot would be too big, also. In use, it's proven to be a non issue. It would be difficult to engage a 1 MOA target with great precision, but I have other rifles and scopes for that purpose.
The .2 mil adjustments irk me as well. Getting a zero is an exercise in compromise. However and again, in use it's irrelevant. I use this scope for faster shooting against larger targets, and it's great for that.
I'd say it's effective for targets in the 2.5-3 MOA size and larger.
I'm toying with the idea of buying the Atacr, too. The reticle is obviously better, but the size and weight would be hard to get used to after the NX8.
I'm not so far from you. Feel free to drive up and take a peek.
