Yeah that process should work for anyone loading for secant OGIVES. Misspelled it in my post above.
Tangent ogives center in the throat more easily, and are less sensitive to seating depth. They also have poorer BC. Berger's Classic Hunter line has a tangent profile where bullets contact the throat, and that is the science behind their Hybrid design: first thousandths of the nose off the bearing surface have a tangental profile, and the rest of the nose has a VLD profile. This makes them less sensitive to throat geometry and seating depth.
