A modern shotgun slug is a heavy lead, copper-covered lead or other material (like steel〔http://ddupleks.com/index.php/en/advantages.html〕 or wax) projectile, with or without a plastic tip, that may have what appears to be rifling, but these are special cuts in the slug to let it deform when passing through a tight choke. Slugs are intended for use in a shotgun and often used for hunting large game. The first effective modern shotgun slug was introduced by Wilhelm Brenneke in 1898, and his design remains in use today. Most shotgun slugs are designed to be fired through a choked smoothbore barrel; they must be self-stabilizing in the absence of rifling. Earlier types of slugs were also used in 4 bore guns intended for hunting dangerous African game in the 19th Century. Such 4 bore guns were produced in both rifled and non-rifled versions. Similarly, modern shotguns have been produced with rifled barrels, or rifled choke tubes, and slugs designed to be fired from them use spin stabilization. As these specialized shotguns are far more accurate than a smoothbore gun, they also usually have a mount for an optical sight, such as a scope. Many of these slugs are saboted sub-caliber projectiles, resulting in greatly improved external ballistics performance. Slugs made of low-density material, such as rubber, are available as less lethal specialty ammunition. A shotgun slug is typically far more massive than a rifle bullet. One common 30-06 bullet, for example, weighs 150 grains (10 g). The lightest common 12 gauge shotgun slug is the 7/8-oz slug, which weighs approximately 383 grains (25 g). ==Uses== Shotgun slugs are used to hunt medium-large game at short ranges by firing a single large projectile rather than a large number of smaller ones. In many populated areas, hunters are restricted to shotguns even for medium to large game, such as deer, due to concerns about the range of modern rifle bullets. In such cases a slug will provide a longer range than a load of buckshot, which traditionally was used at ranges up to approximately 25 yards (22.8m), without approaching the range of a rifle. Less lethal slugs are often used as the main ammunition for police riot shotguns. The slugs will provide accuracy sufficient for antipersonnel use out to ranges of about . This allows the officer the ability to use the shotgun as a reasonable substitute for a rifle at medium ranges, with more stopping power at close range. The shotgun allows the operator to quickly eject a chambered buckshot cartridge and replace it with a less-lethal cartridge such as a bean bag round, instead of being required to unload the magazine as with most rifles or handguns, allowing the officer to adapt to changing situations in switching between lethal or a less lethal ammunition for the same firearm.〔(【引用サイトリンク】format=PDF )〕〔(【引用サイトリンク】title=Taser XREP )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Shotgun slug」の詳細全文を読む スポンサード リンク
