Researchers at the National Institute of Standards and Technology (NIST) are measuring precisely the disintegration of "frangible" bullets when they strike a surface to better understand how the ...

This means that full-power frangible bullets can be shot at target all the way up to muzzle contact without any worries that the bullet or case will ricochet and potentially hurt either the shooter or ...

The Radically Invasive Projectile, or RIP bullet, uses machined copper-tipped bullets to make multiple penetrations into a target, including the main body of the bullet, creating up to nine different ...

Strain waves traveling at 5,000 meters per second in the NIST Kolsky bar apparatus compress a test slice from a frangible bullet to measure the precise amount of stress needed to break it apart.
