No they didn't The Black Talon handgun bullet is a jacketed hollow-point bullet with perforations designed to expose sharp edges upon expansion.[2] The bullet included a Lubalox coating, a proprietary oxide process,[3] (though widely misreported to be Teflon, molybdenum disulfide, or wax) giving it an unusual black appearance compared to other copper-jacketed or lead bullets. The Lubalox coating was to protect the barrel rifling, and did not give the bullet armor-piercing capabilities. This coating in fact is still widely used on many of Winchester's rifle bullets today.[4] The bullet also had a unique appearance with a star shaped perforation on the black tip, giving it the nickname Starpoint.
The bullet was designed in 1991 under the supervision of Alan Corzine, who at that time was VP of research and development for Winchester.[5] The round quickly developed a reputation amongst shooters, law enforcement, and dealers as a very effective bullet, though this was likely a result of media hyperbole than test or field data from actual shootings considering the short time it was on the market. Col Leonard J. Supenski of the Baltimore County police department said "It has the stopping power that police officers need and it is less likely to ricochet or go through the bad guy,"[2] something that could be said of any reliably expanding hollow-point. And despite its unique design, the Black Talon was in fact found to be comparable in performance to conventional hollow-points. In the first shooting which brought critical media attention [6] to the Black Talon, Gian Luigi Ferri used a mixture of them and other ammunition to shoot 15 people at a San Francisco law office in 1993; nine of them died. Dr. Boyd Stevens, the San Francisco Medical Examiner who performed the autopsies, later reported at the 1994 International Wound Ballistics Association's conference in Sacramento that the wound trauma caused by Black Talons was unremarkable and that all victims died due to penetration of a vital structure.[7]
In 1993 Winchester removed the ammunition from public sale but Black Talon ammunition was NEVER uniformly prohibited by US law. Winchester's Ranger SXT line of ammunition is of the same basic design.
Oh wait, sorry apparently San Francisco did ban Black Talons about 20 years after they took them off the market
San Francisco's Black Talon Ban Comes a Little Too Late
