Don, Nikon does not swap out reticles on their scopes. I have heard of companies doing it ont heir high end ( $1800 and up) lines, but Nikon has never done that.
By the way, I love Antelope, Ore., it's been a long time since I have ben in that part of the country but I still miss it!
Sorry I can't be more helpful to you . Have you checked out Spot On, Don? It really is a useful tool for long range shooting. I know a lot of guys can't wrap their head around the BDC reticle, just not the way they learned how to shoot, heck, I was one of those guys until I tried it out.
