Take a look at the Pride Fowler lineup. They just came out with a very nice little scope with 300BO specific reticle. It comes standard with three illumination colors and the glass is very nice. I purchased two of them at pre-production pricing but I think even now they're only running about $400(ish).
I did a lot of research on Pride Fowler and they are little known but very respectable. I am very satisfied with mine.
Just as background; I own several very high end scopes and therefore am somewhat critical but I too wanted a "decent" piece of glass for my "toy" rifle so didn't want to break the bank for it. I thought for what I paid, I would take a chance. Very glad I did.
Hope this helps.
