8-32 benchrest. I knew that would ruffle feathers here but its the truth. I've looked through a number of NF scopes, br and nxs and I really don't like their glass. I'll get flamed for this but here is my take on the NF fetish:
NF makes a great scope, they are very tough and dependable.
They are not however, the be all end all of optics.
Their glass is mediocre at best, a number of companies (yes even some that aren't as expensive) have better optics.
Their reticle selection is sub par.
So why are they so popular?
Crowd mentality. If its more expensive its better, has to be!
If you are deployed in a combat theater than a NF could very well be a great choice. They are tough, repeatable and can evidently take a bullet and keep functioning, all very important attributes when your targets shoot back.
How many of us stateside are in that situation? Yes hunting in the back country can be a little rough but honestly how many of us throw/drop our rifles down a ravine before carrying on with our planned hunt?
We like to think that if x amount of F-Class or other shooters are using a NF than by God we need one too! Ok, go buy one, shoot it well and be happy.
I too disregarded Vortex and others until I did an actual back to back comparison and saw a marked advantage in them over the NFs. Zeiss and Swarovski come to mind.
I'm not anti NF, I have just come to understand that there are other available options that may fit certain applications better than what they are offering.
For those that feel that they HAVE to run a NF, great choice, you will be well served.
For those that look at more than a name brand- lots of options that may be a better fit for what you;re doing.
