And an answer other than "I would but you wouldn't understand" would be helpful.
edit|: Paul Kopsch (an Ohio coroner), Daniel Turcos (a police sergeant), and Donald Ward (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, such as windshield glass and automobile doors. After some experimentation with steel rounds, the officers settled on a brass core with a lubricating jacket of Teflon. These bullets wore-out barrels far more quickly than normal jacketed rounds, as unlike lead the immalleable brass did not deform to fit the rifling. For this reason, the bullets were then coated with a layer of Teflon to reduce barrel wear.
I must apologize for assuming your lack of knowledge of weaponry.
I had assumed you were referring to what the general public believed were Armor Piercing... much of it media fuled with had nothing to do with a bullets ability to defeat common bulet proofing materials. Much like all that hoopla regarding the black "talon" bullets.
I did not realize you were aware of the testing conducted using teflon as well as other materials (I believe Moly Difuside something or other lol - used as dry lube) is also used in this regard.
I digress from the point but I believe winchester and federal now have a special "bonded" bullet where the jacket and the core are actually "bonded" -chemically I believe- so there is less seperation upon impact thus allowing deeper penetration.
Getting back on topic:
Hopefully there is an update of some sort... I checked out the site but no such luck. A lot of times, unless it is pushed, things like this get swept under the rug. Either he will drop the complaint or the city will offer some type of pay off.
