Ever notice that the scope companies that spend a lot on advertising in Outdoor Life Mag never get a lowwer rating even when compared to scopes much better optics?
I stopped reading Outdoor Life and Field & Stream about 30 years ago. The more I got into the *real* world of Hunting, Fishing, Shooting and Outdoors, the more cheezy their articles looked to me.
They live off of advertizing... not good to bite the hand that feeds you...
Never put any stock into a review that accepts $$$ from a sponser, etc.
I listen to real folks, like the ones in these forums. Everyone has some personal preferences but overall, if you read and listen to enough opinions, you see trends and can usually makes some good judgements. There are a handfull of scopes at the very top of the pile and NF is one of them. I have looked through them and they seem to be of excellent optical quality, but that is only one of their outstanding features. And I am getting one.
90% of the scopes on store shelves would be totally ruined by the tests that NF scopes go through.
IMHO, in the long range game (500 yds +), which I am totally new to, you want a scope like a NF, USO, S&B, etc.
I have come to the conclusion, that over 400 yds I will range and dial, and a lot of production *good quality* scopes just do not have the reliable tracking and repeatability of the scopes that are specically designed for that.
BTW, I believe the 6500 has a 30mm tube. Probably a great scope, but not one I would use over 500 yds. JMO
