Taking the idea of “light and fast” model to new levels, the Civil Defense projectiles weigh in at well under half that same caliber traditional bullets. For example, the 9mm projectile weighs just 50 grains. Compare that to 115 or 124 grains for common 9mm defense rounds. The 45 ACP bullets weigh in at 78 grains as compared to a more traditional weight range of 185 to 230 grains. The result is blistering speed. The 9mm ammo is factory rated at 2,000 feet per second while the 45 claims 1,900 feet per second. Even with those velocities, recoil is shockingly light, owing to the the super light bullets.
When you look into the “hollow point” cavity of a Civil Defense bullet, you’ll see a seemingly bottomless hole. The cavity is cut nearly of the base of the bullet itself. I described it as a hollow point, and it appears that way, but it’s not designed to expand in the traditional manner. The idea behind the bullet design is that the solid copper, nickel-coated projectile will pass through barriers without major upset or deformation. When it hits an organic target (read liquid-filled), the pressure of liquid against the interior of the cavity causes the projectile to blow up into multiple fragments. The bullets aren’t scored, cut, or pre-fragmented, they just break apart from fluid pressure. The desired results is a big would channel followed by 10 inches or so of penetration from the base of the projectile.
