The ogive radius ρ is not determined by R and L (as it is for a tangent ogive), but rather is one of the factors to be chosen to define the nose shape. If the chosen ogive radius of a secant ogive is greater than the ogive radius of a tangent ogive with the same R and L , then the resulting secant ogive appears as a tangent ogive with a ...
bullet nose design incorporating a secant ogive, tangent ogive, Von Kármán ogive or Sears-Haack profile [3] the use of tapered bullet heels, also known as boat-tails [ 1 ] a cavity or hollow in the bullet nose ( hollow point ) to reduce weight while shifting the projectile's centre of gravity rearwards [ 1 ] to improve stability with ...
G1 or Ingalls (flatbase with 2 caliber (blunt) nose ogive - by far the most popular) G2 (Aberdeen J projectile) G5 (short 7.5° boat-tail, 6.19 calibers long tangent ogive) G6 (flatbase, 6 calibers long secant ogive) G7 (long 7.5° boat-tail, 10 calibers tangent ogive, preferred by some manufacturers for very-low-drag bullets [12])
A secant ogive of sharpness = / = The ogive shape of the Space Shuttle external tank Ogive on a 9×19mm Parabellum cartridge. An ogive (/ ˈ oʊ dʒ aɪ v / OH-jyve) is the roundly tapered end of a two- or three-dimensional object. Ogive curves and surfaces are used in engineering, architecture, woodworking, and ballistics.

A spitzer bullet (from German: Spitzgeschoss, "point bullet") is a munitions term, primarily regarding fully-powered and intermediate small-arms ammunition, describing bullets featuring an aerodynamically pointed nose shape, called a spire point, sometimes combined with a tapered base, called a boat tail (then a spitzer boat-tail bullet), in order to reduce drag and obtain a lower drag ...
