Ogive ?
I see bullets that a few manufacturers list a bullet and give an Ogive number of a certain bullet.
Examples; .17 Caliber offerings. · *16 grain FB, HP, 6s ogive (drawn from .22/.705" jackets) · 22.5 grain FB, LT, 7s ogive (J4–.460 jacket) · 26 grain FB, HP, 7s ogive (J4-.560 jacket) · 26 grain RBT, HP, 7s ogive (J4-.560 jacket) · 26.7 grain LT, FB, 7s ogive (J4-.560 jacket) · 27.5 grain LT, FB, 7s ogive (J4-.560 jacket) · 29 grain FB, HP, VLD (J4-.635 jacket) · 32 grain RBT, HP, 7s ogive (J4-635 jacket) How is this number found? What is it's meaning? How do I determine a bullet's Ogive number on bullets? What is the effect on a bullets performance? |

The number refers to the distance in bullet diameters. Ie 6D is 6 diameters away and 7D, you get the pic! |

There is a nice schematic and explanation on here for tangent and secant ogive.

Seems like a lot of the Hornady rifle bullets are secant ogive.
