"HOLEY" BULLETS: FASTER THAN THE BULLET WE KNOW
The secret? The bullets have go-faster holes in them.
Available in several calibers, the copper alloy bullets have a main cavity in the base, with multiple "vents" machined into their sides. These reportedly serve several purposes.
First of all, when the gun is fired, the vents supposedly allow the propellant gases to go through the sides of the bullet, providing lubrication between it and the inside of the gun's barrel.
At the same time, the gases shooting out of the vents are also said to create a rocket-like effect, increasing the bullet's velocity. All of you physicists are welcome to weigh in on this one, but it's hard to say if gases exiting the sides of a bullet would really cause it to travel any faster than gases that were limited to pushing on it from behind.
Additionally, CompBullets are claimed to produce less muzzle flash and less smoke. If nothing else, all those holes probably make them lighter than regular bullets, to boot.
