- The spitzer bullet (or spire point) is a pointed projectile that is primarily used in small-arms. The pointed nose shape, which was developed for military purposes in the late 19th and early 20th century, was a major design improvement compared to earlier rounder or flatter-tipped bullets because pointed nose shapes were less susceptible to external ballistic factors like drag. By adding a point, projectiles made for fully-powered and intermediate rifle cartridges, obtain a lower drag coefficient which makes them decelerate less rapidly. Lowering the drag coefficient leads to improved external ballistic behaviour. (en)
- Гостроноса куля (spitzer bullet) — це куля для вогнепальної зброї розроблена наприкінці 19-го напочатку 20-го століття, обумовлена прагненням військових отримати кулю з кращою аеродинамікою, що давало кращу точність та кінетичну ефективність, особливо на великих відстанях. Щоб досягнути цього метальний снаряд повинен мати мінімальний опір в польоті. Назва «spitzer» є англіцизованою формою німецького слова Spitzgeschoss, буквально це перекладається «загострений снаряд». Більшість гостроносих куль використовують у проміжних набоях та потужних гвинтівкових набоях. (uk)

- The spitzer bullet (or spire point) is a pointed projectile that is primarily used in small-arms. The pointed nose shape, which was developed for military purposes in the late 19th and early 20th century, was a major design improvement compared to earlier rounder or flatter-tipped bullets because pointed nose shapes were less susceptible to external ballistic factors like drag. By adding a point, projectiles made for fully-powered and intermediate rifle cartridges, obtain a lower drag coefficient which makes them decelerate less rapidly. Lowering the drag coefficient leads to improved external ballistic behaviour. The development of spitzer bullets and long-range volley sights for service rifles changed military doctrines. Area targets at ranges up to 1,420–2,606 m (1,550–2,850 yd) could be subject to rifle fire. With improvements in machine guns at the turn of the 20th Century, the addition of clinometers meant that fixed machine gun squads could deliver plunging fire or indirect fire at more than 3,000 m (3,280 yd). Spitzer bullets greatly increased the lethality of the battlefields of World War I. Before, during and after World War I, militaries adopted aerodynamically even more refined spitzer projectiles by combining a pointed nose shape with a slightly tapered base at the rear, called a boat tail, which further reduced drag in flight. These projectiles were known as spitzer boat tail bullets which increased the maximum ranges of fully-powered rifle cartridges to between 4,115 and 5,500 m (4,500 and 6,010 yd). (en)
