There was a great article I found on here that would be very similar to what you could do with the BDC reticle: No Click LR carry gun
This is similar to what I plan on doing with my Monarch BDC. Pick a few areas to have the BDC dialed in (i.e. 16x, 12x, 8x) and put the numbers on a piece of paper that is taped to my gun. Using Nikon's ballistic program will help this a bunch, but as has been said, the only real way to find out if it is exact is to get out and shoot. Good luck!
