In the 1960s the Yugoslavians experimented with new bullet designs to produce a round with a superior wounding profile to the M43. The Yugoslavian type rounds are known as M67 and incorporate an air gap inside the front of the bullet. This shifts the center of gravity rearward, causing the bullet to destablize nearly 17 cm earlier in tissue. This causes a pair of large stretch cavities at a depth likely to cause effective wound trauma. When the temporary stretch cavity intersects with the skin at the exit area, a larger exit wound will resul ...

The development work that would eventually develop into the 7.62 × 51 started just after World War I, when it became clear that the long cartridge of the US standard .30-06 round made it difficult to use in semi- and fully-automatic weapons (the .30-06 was in turn derived from an earlier .30-03 cartridge, and had more case capacity than was needed). A "shorter" round would allow the firing mechanism to be made much smaller, and improve the feeding, both of which would allow for higher rates of fire. At the time one of the most promising des ...

The 5.56 NATO cartridge with the standard military ball bullet (NATO: SS109; U.S.: M855) will penetrate approximately 15 to 20 inches (380 to 500 mm) into soft tissue in ideal circumstances. As with all spitzer shaped projectiles it is prone to yaw in soft tissue. However, at impact velocities above roughly 2,700 ft/s (820 m/s), it will yaw and then fragment at the cannelure. The fragments disperse through the flesh causing much more internal injury. The effectiveness of fragmentation seems to impart much greater damage to tissue than bullet ...
