Re: Nightforce blurry
Reticle focus and parallax adjustment is always touchy on NF scopes. Each one I've had to adjust the diopter over multiple outings in order to get proper focus of the reticle. I've noted that what "appears" to be the sharpest reticle when adjusting the eyepiece diopter tends to not be the best solution for the best balance between reticle and background(parallax focus).
What seems to work for me, is to point it at the sky so that I'm looking at infinity and have no scale reference for my eye to try and focus on. Set parallax to infinity and then back off a hair. (I just don't believe that full extents is true infinity. Lots of times infinity is back a bit. Focusing on the moon helps to discover this. Something I've only done with my spotter.) Then start adjusting the diopter eyepiece focus. When trying to focus the reticle I keep going on and off of the scope, trying to get focus as soon as I make a good sight picture. Don't stay on long because my eyes refocus and will bring the reticle into focus for a false diopter setting. Take a break, rub eyes, look far, look close, check focus again. Repeat.
At a certain point you'll hit a focus where it's sharp, but when you adjust it past that it will seem to become higher contrast. Like it stands out more. For me, it almost looks like the reticle has a brightening effect around it's edge. Don't go this far! I think it is what really messes up parallax adjustment. Get it so that the reticle is within acceptable focus as soon as you get on the scope. Adjust it over Multiple outings to compensate for a variety of lighting conditions.
After this, adjust parallax purely based off of seeing parallax shift.(Move eye off optical center and see if the reticle shifts in relation to the background.)
With it adjusted like this, you should be able to focus at just about any distance on max magnification outside of 150yds. I've noted that no matter what I do all my NF scopes with max mag above 10x seem to suck at focusing closer than 150yds. Of course if you're shooting that close high mag and a perfectly crisp reticle isn't needed. And if it is, you buy the benchrest series of NF scopes.
Also, everyone's eyes are different. I have Astigmatism and I am Near Sighted. I am fighting my own physical flaws in order to achieve a sight picture. Because of this, I don't expect optics to have perfect clarity when I look through them. Something to consider if you also have corrected vision.
