BTW, though illegal right now in the States, arcane bullets are a very low-tech and effective anti-armor round, and are easily made. They were originally developed in Germany during WWII. Just mill pure copper or soft brass to a somewhat smaller diameter than the lead bullet would have (copper and brass are harder than lead, so chamber pressures go up - one would start right at the diameter of the rifling, and increase the diameter slowly from test to test paying attention to primer and case deformation). The front of the bullet is simply milled to a 45/90/45 degree cone (sharp tip). High velocity (1400+ FPS from a .45 ACP), and goes through body armor and metal very nicely according to the old Guns and Ammo issue I read. Lots of wound damage as well, from what it said. One never knows when this kind of information (as well as a machine shop) might come in handy...
Surprisingly, I wasn't able to find much information about arcane bullets using Google...strange.
P.S. Looking around on the web, it appears that AP ammunition is only prohibited if it is "A handgun projectile wholly made of tungsten alloys, steel, iron, brass, bronze, beryllium copper, or depleted uranium" or "A handgun projectile larger than .22 caliber with a jacket weighing more than 25% of the total weight of the projectile." So, it appears the pure copper form is legal to manufacture, at least for the time being... It also appears from the wording there that copper jacketed steel cored bullets should be fine as long as the jacket is less than 25% of the total weight...hmmmm. :-)

This stuff does not work nearly as well in real life as in the ads...
