BULLET STABILIZATION The act of steadying a bullet in flight by use of the proper rifling twist and bullet velocity. BULLET TIPPING The instability of a bullet in flight. Sometimes referred to as keyholing. BULLET TRAP A device to safely stop a bullet in flight. Usually found in indoor ranges behind the target area. BULLET UPSET In Interior Ballistics: The change of bullet form due to chamber pressure. In Exterior Ballistics: The expansion of a bullet upon impact with target. BULLET, BOATTAIL A specific design of bullet having a tapered or truncated conical base. BULLET, CAPPED Consists of a standard lead type bullet having a harder metal jacket (gilding metal, copper, etc.) over the nose. BULLET, CAST A bullet formed by pouring molten lead alloy into a mold. BULLET, COATED Lead bullet, having a thin coating of another material such as brass, copper, nylon, etc. BULLET, COPPER JACKETED A bullet having an outer jacket of copper or copper alloy, and containing a lead alloy core. BULLET, CORE The inner section of a jacketed bullet, usually lead. BULLET, DISINTEGRATING See Bullet, Frangible. BULLET, DUMDUM An obsolete term referring to an expanding bullet manufactured at the British Arsenal in Dumdum, India around 1900. BULLET, EXPANDING A hunting bullet design that provides for controlled expansion upon impact. BULLET, EXPLODING A bullet containing an explosive in the nose, intended to explode on impact. BULLET, FLAT-NOSED A bullet with flattened front end at right angles to the axis. BULLET, FRANGIBLE A projectile designed to readily break up upon impact on a hard surface in order to minimize ricochet or spatter. BULLET, FULL METAL CASE See Bullet, Full Metal Jacket. BULLET, FULL METAL JACKET A projectile in which the bullet jacket encloses most of the core with the exception of the base. Also called Full-Jacketed, Full Patch, Full Metal Case. BULLET, GALLERY See Bullet, Frangible. BULLET, GAS CHECK A lead alloy bullet with a copper or gilding metal cup pressed over the heel. BULLET, HOLLOW BASE A bullet with a deep heel cavity. BULLET, HOLLOW POINT A bullet with a cavity in the nose to facilitate expansion. BULLET, INSIDE LUBRICATED A bullet having lubrication in grooves on the bearing surface of the projectile. When seated, these grooves are covered by the cartridge case. BULLET, LEAD A bullet formed by a lead alloy. BULLET, METAL CASED See Bullet, Full Metal Jacket. BULLET, MUSHROOM A bullet that has expanded upon impact into a mushroom-like shape. BULLET, NATIONAL MATCH A bullet manufactured specifically for ammunition issued to competitors at the National Matches. BULLET, OGIVE The curved forward part of a bullet. BULLET, OPEN POINT EXPANDING See Bullet, Hollow Point. BULLET, OUTSIDE LUBRICATED A lead bullet lubricated on the surface not covered by the cartridge case. BULLET, PARTITION A bullet designed for controlled expansion having a jacket which is divided into two cavities which enclose the forward and rear cores of the bullet. It is designed so the first cavity expands and the rear cavity holds together for penetration. BULLET, PLATED The entire bullet, or just the jacket, electrolitically plated with a different material. BULLET, PLUG 1. A device used in scoring bullet holes in a paper target.2. A pin inserted in a bullet mold to form a cavity in the nose or base of a bullet. BULLET, ROUND NOSE An elongated projectile with a radiused nose. BULLET, SEMI-JACKETED A bullet with a partial jacket exposing a lead nose. BULLET, SEMI-JACKETED HOLLOW POINT A projectile having a jacket exposing a lead nose with a cavity. BULLET, SEMI-WAD CUTTER A projectile with a distinct shoulder and short truncated cone at the forward end. BULLET, SOFT POINT A design providing for exposure of a portion of the core at the nose of a jacketed bullet. BULLET, SPENT A bullet which has lost all of its kinetic energy. BULLET, SPIRE POINT A bullet with a near conical ogive. BULLET, SPITZER A bullet design having a sharp pointed, long ogive, usually of seven calibers (i.e. length to diameter ratio of 7 to 1.)or more BULLET, STEEL JACKETED Plated or clad steel is sometimes used as a substitute for gilding metal or copper in bullet jacket material. BULLET, SWAGED A bullet that has been completely formed by impacting the bullet material into a die. BULLET, TOTAL METAL JACKET Bullet made by copper plating a lead slug to create a jacket that completely encases the core. This jacket is thicker than cosmetic copper plating BULLET, TRUNCATED A design of a flat-nosed bullet having a conical shape rather than a nose formed by a radius. BULLET, TRUNCATED CONE A design of a flat-nosed bullet having a conical shape rather than ogive formed by a curve or radius.
