I would suggest that you not do the BDC unless you plan on shooting the loads that Nikon indicates - even then every gun is different. What I would suggest and what I do is place a scope on with a Ballistic Reticule or a Mil-Dot reticule. With these types of reticules you can shoot the ranges and verify what the actual drop of your projectile is and which reticule line to use at a given range.
Nikons are very good scopes - but I prefer the Bushnell Elite 3200 with a Ballistic Reticule....

This is a mil-dot reticule to compensate for elevation and windage...
Looking for a an example of the Ballistic reticule
found one.... this the one I use and I do prefer the 3x9x40... $238.00 @ scopes 'n more probably more expensivethan the Nikon, but in combination with the "rain Guard lenes and the reticule it is a great scope....
