Scope is fine. The B&C reticle is simply their version of a BDC type reticle that also allows for some wind drift. I really like reticles with multiple aiming points, but this one is just too busy for my tastes. That doesn't mean it is bad, just my personal preference.
I wouldn't want a 50mm objective on a hunting scope. They help slightly in low light, but only when the scope is set on 9X or 10X. On any lower magnification, or more magnification a 40mm objective does exactly the same thing. And the 40mm objectives cost less, weigh less, and are easier to mount low on the rifle.
Not enough info to say which rifle it would be best on.
