I have a few of those scopes. I have the Leupold, Nikon, and Burris designs.
I have a Leupold 4.5X14 on my Knight LRH. It has the B&C reticle. And it works very effectively. I would highly recommend this reticle. I have the Burris Ballistic-Plex reticle, and I would rate it second. Not as good as the Leupold, but definitely better than the Nikon.
Then I have a Nikon Monarch with the silly circles. The scope quality is OK. But their circles system sucks(IMO). It is extremely cluttered. I put the scope on a 22 LR and only use the crosshair. If I had to use the circles system I would get rid of the Nikon and buy another Burris or Leupold.
For some reason the Nikon system is popular. But I can not figure out why?? The idea behind the reticle is setting up a precision system for shooting at longer ranges. And the circles just do not allow for that precision. Try the Leupold system. You will like it. Just make sure you spend enough time at the range to know exactly where your rifle is shooting. Tom.
