| What people don't realize is the 7.62mm and the 5.56mm both have their advantages and disadvantages. For one, the 5.56mm actually flies better and penetrates better. Before they made it "too accurate" the 5.56mm had no problems putting that energy into the target because upon impact, the bullet tumbled, transferring the energy extremely effectively. The result were exit wounds the size of a grapefruit (grapefruit, not grape!). This with the superior penetration compared to the 7.62mm. However, the current M-16s... and the current ammo, doesn't tumble the bullet when it impacts. This means the bullet's penetration ability becomes its liability because it just simply glides through the target. |
