I've been doing quite a bit of research on these, and have narrowed it down to three reticles that interest me. This is based on the ability of using their ballistic software as well. Nikon BDC Zeiss Conquest Rapid Z Vortex Dead-Hold BDC My daughter currently has the Nikon on her Savage, and along with the software I have found it to work really well. I tried out both the Zeiss and Vortex software online, and both seemed very usable. The problem with the Zeiss that I have is it seems the reticle lines seem a lot thicker then other scopes I've looked through. I see this as being a problem with longer range shots. The Vortex BDC...well, I wish there was more lines on it rather then just a few, seems like it would be hard to get those ranges in between. I'd love to hear any comments on any of these, pro's or con's from those that are or have used them. It will be very helpful in me making my final decision. Thanks in advance!
