How Does Crossbow Work?

A crossbow is now a popular weapon. Due to its unique properties and power, many bow hunters prefer crossbows over regular bows. Certified hunters are using this weapon to shoot their targets during the firearms season. For a beginner, it might be a question how does the crossbow work? Any specific course is not needed to understand the complete procedure. All you have to do is understand the concept of crossbows and practice from different angles. Then, you are good to go to the hunting field.

This guide will answer all your questions related to the working of the crossbow. Different parts of the crossbow make a successful shot possible. So, it is important to understand the function of each part. Let’s explore the working of a crossbow.

How Does Crossbow Work?

The crossbows have some features of rifle and bow. They are equipped with stock and trigger, similar to a riffle, but like a regular bow, crossbow uses a string for projectiles. The crossbow’s working principle is similar to other bows but differs in power and speed.

Working:

Crossbows store energy in their limbs. The energy is transferred to the crossbow’s arrow when the string is released. The first step is to cock the crossbow. The crossbow string draws the limbs close together as a result of cocking. In this way, elastic potential energy is generated in the limbs. The moment when you release the string, elastic potential energy converts into kinetic energy. Hence, energy is transferred to the arrow.

Variations in modern crossbows have been happening over the years, but the basic concept of a crossbow remains the same; to convert elastic potential energy into kinetic energy. Just like other bows, crossbows do have limited range. So, for a lethal shot, careful estimation and precision of distance are required.

Let’s go through the common parts of the crossbow with their functions.

Main crossbow parts and their functions:

Understanding the working of the main parts is crucial to maintain the crossbow. After getting familiar with the important parts, it will be easier for you to handle and work with your crossbow.

There are two styles of crossbows; recurve and compound crossbows. Recurve bows are slightly heavier and longer than compound bows. Also, compound bows are considered a more sophisticated and modern version of crossbows; hence, they are easier to use. Both types of crossbows have some common parts. An overview of these parts is discussed in this guide.

Crossbow bolts

Bolts are just like standard arrows but are a little heavier and shorter in size. It would be best if you used a bolt according to the crossbow’s weight, length, and stiffness. Shooting with a mismatched bolt is dangerous for you and the people around you. Crossbow bolts conserve maximum kinetic energy for the launch.

Limbs

Limbs are made up of flexible wood, carbon fiber, and aluminum. When you release the string, the limbs move forward, and the energy in the limbs launches the bolt at high speed. Limbs are present in the compound and recurve crossbows. Recurve crossbows have longer limbs than compound ones.  

Foregrip

While holding a crossbow, one hand is the trigger hand; the other hand will grip a point called a foregrip that is present beneath the rail. The foregrip provides sturdy control of the shot. It is necessary to aim at the target; otherwise, a poor shot can wound the animal.

The working of the crossbow

Although crossbows resemble conventional bows and other weapons, the mechanics of a crossbow is distinctive. In crossbows, we cock and load the weapon. So, ensure the safety of the crossbow right after the cocking procedure. Although some crossbows have automatic safety options, in mechanical devices, automatic safety can fail at any time. So, keep checking the safety of the cocked crossbow.

Once you are done with the shooting, crossbows must be decocked. Dry firing is not a good option for decocking the crossbow. Shoot the loaded bow into a backstop.

a compound crossbow:

Unlike recurve crossbow, a compound crossbow works on the principle of block and tackle. A crossbow’s draw weight is reduced by using the draw weight system. The let-off function makes the compound crossbow different from the other bows. The cables and the strings combination work for the let-off function.

Working:

The cam starts to rotate when we draw back the string. The mod also rotates when the cam rotates as the mods are attached to the cams. The rotating mod will pull the cable. Cable and mod are the only requirements to bend the crossbow’s limbs. As the cable and limb are in the attachment, the limb will bend. This bending of limb creates the draw weight in a compound crossbow. The pulleys allow the string to increase the speed and power of the shot.

a self-cocking crossbow:

A self-cocking crossbow is easier to handle and lightweight, but it does have some cons, as you have to check safety while cocking the bow. When you cock the crossbow, the weapon does not always engage the safety. So, ensure safety before each shot.

Working:

In the first step, assemble the crossbow. The cocking mechanism of a pistol or self-cocking crossbow is very quick and easy. It will take less than 30 seconds to load the weapon. Then, the string is attached to the latch. Afterward, the next bolt is loaded, cocked, and fired again.

working of a repeating crossbow:

A repeating crossbow is a crossbow in which actions like bolt placing, stringing the bow, and shooting can be done instantly in one motion. As all the major actions happen simultaneously with just one hand, the fire rate of repeating crossbows is higher than other standard crossbows. Repeating crossbows hold only five bolts at a time.
