I have 2 B&C Leupold scopes. They are O.K. in low light.. but just so so.I have pretty much quit using Leupolds. I prefer ballistic reticles in 1st focal plane instead of 2nd focal plane as Leu. and Zeiss. The 2nd focal plane scopes are most accurate at 1 certain power for particular bullet load. Have had good success with Pride/Fowler Rapid Reticle scopes, with reticle in 1st. focal plane accurate at all magnification powers. The Zeiss Rapid reticle is O.K. better in low light than Leu.
Pride/ Fowler developed the Rapid Reticle with Zeiss. Zeiss used to give credit to P/F for that technology. I do not believe that acknowledgment is on Zeiss website any more.
IMO Leupold has been playing catch up in reticle dept. Out of 60+ scopes over the years have had most trouble with Leu. Last problem [ parallax] Leu. couldn't solve.
