在60年代中, Paul Kopsch 博士(俄亥俄州的法医), Daniel Turcos(警官), 和Donald Ward(Paul 的特别探员)开始实验一种特殊用途的手枪弹药. 他们的目的是开发出一种专供执法部门使用的, 能更好的穿透象挡风玻璃和车门这样的硬目标的子弹. 一般的子弹主要是用铅制成, 对硬目标不是很有效, 特别在用手枪发射时. 在70年代, 他们开发出了有极强穿甲能力的"KTW"钢芯手枪弹. 在更多的实验之后, 他们在1981年开始生产主要以铜为芯的子弹. 但这种硬铜芯的手枪子弹会很严重的磨损手枪的枪管. 于是, 他们在子弹上涂Teflon(特富龙)来减轻这个问题. 就是说, 这个Teflon涂层不是用来提高穿甲性能的, 它只是用来降低子弹对枪管的损害的.
虽然KTW子弹从来没有向公众出售过, 也没有警察因为被这种子弹打穿防弹衣而殉职, 媒体还是错误的报道说这种子弹是专们设计用来击穿警用防弹衣的. 这也就是"警察杀手弹"的由来.

原文:
In the mid 1960's, Dr. Paul Kopsch (an Ohio coroner), Daniel Turcos (a police sergeant) and Donald Ward (Dr. Kopsch's special investigator) began experimenting with special purpose handgun ammunition. Their objective was to develop a law enforcement round capable of improved penetration against hard targets like windshield glass and automobile doors. Conventional bullets, made primarily from lead, are often ineffective against hard targets especially when fired at handgun velocities. In the 1970's, Kopsch, Turcos and Ward produced their "KTW" handgun ammunition using steel cored bullets capable of great penetration. Following further experimentation, in 1981 they began producing bullets constructed primarily of brass. The hard brass bullets caused exceptional wear on handgun barrels, a problem combated by coating the bullets with Teflon. The Teflon coating did nothing to improve penetration, it simply reduced damage to the gun barrel.
Despite the facts that "KTW" ammunition had never been available to the general public and that no police officer has ever been killed by a handgun bullet penetrating their body armor, the media incorrectly reported that the Teflon coated bullets were designed to defeat the body armor that law enforcement officers were beginning to use. The myth of "Cop-killer" bullets was born. |
