Rubber bullets are (usually) not lethal, but these new plastic bullets are

The website-with-an-obvious-viewpoint, BearingArms.com is reporting that polymer bullets are under development. The bullets are actually a polymer/copper composite (no idea of what the relative amounts of each are), but since they have less mass than a traditional round, there is less recoil when fired. But more interesting than the materials is the shape of the bullet. Take a look:
Plastic Bullets
They are rounded in the front (like many other ammunitions), but also scalloped in three locations. This design was not accidental (few designs ever are) and testing on ballistic gel has shown that this feature increase the lethalness of the bullet. Go to the article if you want the details; they are not appropriate for this column.

This opens the door to future designs that are even more "creative", since working with plastics is generally much easier than working with metals. And since we already have 3-D printed guns, it won't be too long before we have 3-D printed bullets too.
