‘caliber of ogive’ just seems a misuse of ‘ogive radius’ which in ballistics, is expressed in calibers.

The trick remains: determining ogive radius.

For hybrid bullets the radius of curvature changes. If you can obtain the minimum and maximum curvature radii, then you could calculate the range of calibers of ogive, but these minimum and ending radii are not normally provided by the bullet makers.

How will this formula work (if at all) when using ‘hybrid’ projectiles, for instance the Berger hybrids?
If I’m correct, they have no clear radius but more like two radii.

In the second diagram, .264 should replace .308.

Thanks for posting this. I have always wanted to know how to calculate this.
