Most of our traditional Hunting Bullets are spire points with a secant ogive design for ballistic efficiency. Most also feature our exclusive InterLockÖ (IL) design for enhanced terminal performance. Secant Ogive Design Pioneered by Hornady for use in hunting bullets, this technology broke new ground in ballistic engineering and is now used in bullets for everything from match to varmint shooting. The secant ogive is a geometrically developed design that creates the most ballistically efficient profile, yet retains the optimum bearing surface. The combination of the slender point and increased bearing surface results in lower drag, increased stability, flatter trajectories and amazing accuracy.
