BHP - Bonded Hollow Point. Same as the JHP, but the metal jacket has been chemically bonded to the lead core to ensure that the jacket cannot separate from it on impact. This is desirable for when a bullet may need to penetrate glass or thin metal and still remain intact.
FMJ - Full Metal Jacket. A bullet completely enclosed (except for the base) in a hard metal jacket (usually an alloy of copper, sometimes mild-steel). This is the only type of bullet permitted in warfare.
JFP - Jacketed Flat Point. Same as the FMJ, however instead of the tip of the bullet being rounded, it ends in a flat plate.
JHP - Jacketed Hollow Point. A bullet constructed of a soft lead core enclosed in a hard metal jacket. The top of the bullet has an opening in the jacket, exposing a hollow lead core. On the force of impact, the bullet is forced to open up and expand, resulting in less penetration but greater damage due to the larger diameter of the now expanded bullet.
JPF - Jacketed Pre-Fragmented. The bullet consists of a metal jacket as in the JHP, but instead of the core being solid lead, it consists of a number of separate projectiles, such as lead shot (the most common), metal disks, or polymer, (or any combination) compressed into the jacket. The tip of the bullet usually has a polymer "cap" with a round-nose profile to ensure reliable feeding. JPF bullets are usually much lighter than normal bullets, and travel at extreme velocities.
JTC - Jacketed Truncated Cone. Very similar to the JFP, but the sides of the bullet are straight and end in a flat plate, as opposed to the JFP where the sides are more rounded. The JTC bullet has the profile of a cone with a flat plate at the tip instead of a point.
LTC - Lead Truncated Cone. Same as JTC, however the bullet is constructed completely of lead and has no metal jacket.
LHP - Lead Hollow Point. Same as the JHP, but the bullet is constructed completely of lead and has no jacket.
LRN - Lead Round Nose. Same as the FMJ, however the bullet is constructed completely of lead, and has no metal jacket.
PHP - Plated Hollow Point. Same as the JHP, however, instead of the lead core being enclosed by a metal jacket, it is instead coated with a thin layer of chemically deposited metal.
SJHP - Semi-Jacketed Hollow Point. Same as the JHP, except the jacket does not completely cover the lead core. Usually a small section (about 2mm or 1/8") at the top of the bullet is left exposed. This is an older design, but is still common in the .38 special, .357 Magnum and .44 Magnum calibers.
SWC - Semi Wad Cutter. Very similar to the LTC, however the base of the bullet has a slight ridge or shoulder. Thus the diameter of the base of the cone is slightly smaller than the base of the bullet itself. This causes the bullet to cut neat round holes in paper targets, instead of ripping the paper.
TMJ - Total Metal Jacket. Same as the FMJ, however, unlike the FMJ where the metal jacket encloses the whole bullet except the base, the TMJ bullet's base is also enclosed by the jacket.

一種在印度達姆─達姆兵工廠發展出來的英國軍用彈頭，曾經於1897 和1898 年在印度西北邊區和蘇丹使用。它的口徑是 .303英吋 British （.303 inch British），金屬外殼沒有完全包覆彈頭前端，彈頭的鉛質核心外露，以增加彈頭效率。這個設計並沒有進一步改良，因為 1899 年的海牙公約（不是1925 年主要處理毒氣使用問題的日內瓦公約）禁止在戰爭中使用這類子彈。「達姆彈」這個名詞經常也被誤用來稱呼各種供打獵用的軟頭彈頭或是中空彈尖的彈頭。
