...penetrates armor.
Saw that mentioned in a thread. |

Are you referring to those Teflon coated bullets that would go right through an armored vest?

I'm only familiar with the old KTW green Teflon coated stuff.
When the KTW ammunition was first put on the market in the late 1960’s, anyone could purchase it. But, it soon become known as “cop killer ammo” as they would easily penetrate bullet proof vests. This was unwarranted as, according to the FBI, no police had ever been killed by anyone using this ammunition. But, because of the misconception, it was soon available only to the police. It was removed from the market in the 1990’s. The bullets were at first made from a type of bronze called Kennertium (non-magnetic) covered with green Teflon. Later they changed to steel (magnetic) covered with Teflon as it worked just as good and was much less expensive to make. The KTW stands for Kopsch, Turcus and Ward, the three inventors of the bullet. The early rounds were headstamped “KTW” but later production used mostly Winchester cases, but can also be found in Remington, Smith & Wesson and other cases. It was made in all major handgun calibers from .25 Auto to .45 ACP. 9mm KTW shown below.   |

The federal legislation banning AP defines it by construction, nothing else. Can't be or have a steel core, bronze, depleted uranium, or a jacket above a certain weight. I think I left out beryllium copper.
The depleted uranium always amused me. They could have left out depleted, as just uranium covers that. |

The old Aguila IQ rounds in 9mm would randomly penetrate level ii body armor out of my glock 19. this was way back in the day. It wasn't consistent. I never bought anymore to try when we switched to iiia when we moved to 357sig.

A law banning uranium also bans depleted uranium. Though economic factors are such that no government ban is required. As far as different properties go, yes, you are correct. But nothing that matters at handgun velocities. |

Don't know if it's commercially loaded, but supposedly...

Soft armor doesn't stand a chance. |

How would a round like BB 147 +P Hard cast fare against armor? I know it’s slow compared to the light penetrators but it also doesn’t deform. Obviously out of a carbine it’ll carry some extra velocity.

Hard cast bullets will deform if they strike a hard target. Also, if they strike layers of Kevlar, (and I assume other types of soft body armor). In the last century I tested hard cast 220 SWCs from a 6" M57 .42 Magnum. Velocity was >1300 FPS. The results were always the same, the bullet would mushroom and be stopped. Similar results from .357 Magnums. Bullets heavier than 147 grains and traveling at velocities higher than a 9mm carbine barrel would produce. Hard cast bullets do well at penetrating a lot of flesh and hide. They even do well at breaking through bone. They don't do well at penetrating soft body armor, at least not at velocities achievable by carbine barrels in 9mm, or magnum revolvers.

Quote HistoryOriginally Posted By RDTCU: Liberty is not classified as AP but will penetrate IIIA soft armor Speed penetrates armor. Some of their stuff smokes along pretty well in a longer barrel. [4-5''] Wonder how it would work in a 12-16'' barrel. |

Depends on the armor
