RE: Scope on 700 BDL
I' ve had good experiences with Leupold scopes....and the couple of times I needed their service department in a 35 year plus span....I had great service. Put on the finish you prefer! If one or the other matches your rifles' finish more closely consider it first. Other wise, it is personal preference.
The matte finish is probably less likely to reflect light than the standard finish....but the truth is that the lens itself is the object most likely to reflect light!
Good luck...with a good scope!
