What Does ACP Mean in Firearms?

Acute means “quick” and Accurized means “using more force than standard”. Because of this reason, APS or Air-Powder Turbulence Control, a bullet with a larger muzzle energy than other bullets, is used by police forces for instance. The question now is what does ACP mean in firearms? Let’s find out.

First, ACP is the collective term for a number of different bullet types. It is generally accepted that all hollow-point ammo and subsonic rimless ammo are ACP by definition, but not all. In order for a hollow-point round to be considered loaded and appropriate for use with guns, it must have a lead tip. Hollow-points are typically less dense than lead, so they weigh less and have a greater bullet drop. The round ends up shooting truer distances because it creates greater wind resistance at the range it’s fired from. ACP is a collective term for those measurements.

The second step is to ask yourself what does ACP have to do with energy transfer in a gun. How is energy transferred through a bullet? Well, a bullet loses its momentum in the air before it leaves the gun’s barrel. Once in the barrel, the bullet loses energy due to gas pressure and friction. Once in the hands of the target, the bullet loses even more energy in the form of kinetic energy which is the product of momentum and time.

So now we know what ACP means, but how is that important? This concept has many applications in modern day shooting. If you want to have maximum accuracy, you want as much energy transfer from your bullet to the target as possible. If you lose energy in the form of kinetic energy, you’ll never hit your target.

It’s important to note that the bullet will lose energy in flight at a certain velocity. How much energy you lose depends on what the bullet was constructed of and what it’s constructed of mixed with the environment. For example, if you take a lead bullet and shoot it at a hundred yards per minute, it will lose energy at a different rate than a steel bore. Remember, the caliber of the bullet and the speed at which it travels affect the amount of energy that the bullet transfers to the target.

This applies to energy transfer as well as the diameter of the bullet that you’re using. If you take a.22 caliber bullet that is a little under three inches long, and you shoot it at one hundred thirty-five rounds per minute, you will achieve about four thousand feet per second or about eight hundred feet per second, which is a significant amount. Now, if you take a five-inch bullet that is the same weight and caliber, it would only transfer about two thousand feet per second or about four hundred feet per second.
