If you start using this as a point to measure off of in your handloads, use a stoney point tool/gauge. RCBS makes "mic's" for a variety of calibers but the stoney point tool is far better for a variety of reasons. These types of tools are not only used for measuring off of a bullet's ogive but also the case shoulder.
To not get technical, the ogive is used to enable a handloader to determine how close the bullet is loaded to the rifling (lands?). Generally, a bullet closer to the rifling will shoot better. I back the bullet off from .010 to .005 if I am remebering correctly. Read instructions that are provided and reloading manuals for their recommendations. The nosler manual even recommends a way of doing this without having a tool. It works, but I prefer my stoney point. Some people even load their bullets where they touch the rifling.
I have also found you get more consistent measurements of a bullet's length when you use the ogive measurement rather than the case's overall length.

Secant ogives, and tangent ogives....but I don't want to drop that on you as of yet!!! /ubbthreads/images/graemlins/laugh.gif
Bullets are funny, Sierra's are very forgiving of throat erosion or free bore, other makes such as the VLD's are NOT. They (like Bergers VLD's) don't like to be much over 0.010" off the lands.
