So, grab your air gun, and let’s dive in!

What Are Firearm Pellets?

Pellets are typically cylindrical or spherical and are designed to be fired from specific types of guns. Pellets can be made from various materials, but the most common material is lead. However, alternative materials like steel, copper, or alloy are also used, depending on the intended use and regulations. And you know the choice of material affects the pellet’s weight, hardness, and other performance characteristics.

The purpose of pellets varies depending on the type of gun and the shooting activity. In air guns, pellets are used as the primary ammunition. They are typically loaded into a magazine or chamber and propelled by compressed air or gas. Air gun pellets are available in different caliber sizes such as .177 (4.5mm), .20 (5mm), .22 (5.5mm), and .25 (6.35mm) to match the specifications of different air gun models.

In serious firearms, pellets are less common and are generally used in specialized applications. For example, certain shotgun shells may contain multiple small lead or steel pellets, commonly known as “shot” which are used for hunting birds or other small game. Shotgun pellets come in different sizes, referred to as shot sizes, ranging from small birdshot (#9) to larger buckshot (#4 to 000).

8 Basic Types of Air Gun Pellets Based on Design

Diabolo Pellets

Diabolo pellets are the most common and popular ammunition for air guns and air rifles. They are named after their distinctive hourglass shape, resembling a diabolo toy. It’s also known as a “waisted” or “wasp-waist” design because it has a narrow waist compared to its head and skirt. Diabolo pellets are typically made of lead, although alternative materials like copper or alloy are also used. The design of Diabolo pellets features a larger head, a narrower waist, and a hollow skirt at the base. Now, you might wonder, what makes this design so special? Well, the diabolo pellet’s unique shape offers two main qualities that shooters value- stability and accuracy. The hollow base allows the pellet to engage with the rifling in the barrel. It improves stability and accuracy during flight.

The great thing about Diabolo pellets is that they come in all popular calibers, so you can find them in .177, .22, and even .20 and .25 sizes. This ensures that shooters using different air guns can benefit from the stability and accuracy provided by this pellet design.

So, whether you’re a target shooter looking for precise shots or a hunter seeking accuracy in the field, diabolo pellets offer a reliable choice with their effective design and availability in various calibers.

Round Nose Pellets

Round nose pellets design features a rounded head that promotes aerodynamic flight. This design helps maintain stability in mid-air. These pellets offer good impact and penetration due to their shape. Thus making them ideal for target practice, plinking, and small-game hunting. Round nose pellets also provide a balance between accuracy and impact. Therefore, they have become a versatile choice for various shooting scenarios.

Hollow Point Pellets

When it comes to hunting small game or pest control, hollow point pellets take the stage. These pellets are designed with a hollowed-out tip which allows for controlled expansion upon impact. The expansion creates a larger wound channel, resulting in efficient energy transfer and increased stopping power. Hollow point pellets are known for their excellent terminal ballistics. So they are highly effective for dispatching small games swiftly and humanely.

Pointed Pellets

As the name suggests, the Pointed pellets feature a pointed tip. This design provides increased penetration and better aerodynamics. So they get higher velocities in flatter trajectories. They also help to improve accuracy over longer distances. That’s why they are an excellent choice for those seeking precise and consistent performance. Moreover, Pointed pellets are often favored by shooters engaged in field target shooting or long-range precision shooting.

Wadcutter Pellets

Wadcutter pellets deviate from the traditional pellet shape with a flathead design. These pellets are primarily used for target shooting and competition purposes. The flat head creates a clean, round hole in the target, making it easier to score and evaluate accuracy. Wadcutter pellets have a lower velocity compared to other types, but they excel in delivering consistent performance and tight shot groups at shorter distances.

Polymer-Tipped Pellets

Polymer-tipped pellets combine the best of both worlds by incorporating a polymer tip on top of a traditional pellet design. Because the polymer tip enhances the aerodynamics and ballistic coefficient which help shooters to maintain the pellet’s shape during flight. And this leads to better consistency and impact performance. These pellets are often used in medium-range shooting for their excellent terminal ballistics.

Solid/Airgun Slugs

Solid or airgun slugs are single-projectile ammunition designed for specific air guns or air rifles. Unlike Diabolo pellets, slugs have a solid construction throughout, without a hollow base. They are usually heavier than pellets and have a more streamlined shape. 

Solid slugs are designed to provide higher energy transfer, better penetration, and improved long-range performance compared to traditional pellets. Slugs are available in various calibers. So it allows shooters to select the appropriate size for their air guns.

Hybrid Pellets

Hybrid pellets are a relatively newer development in the world of air gun ammunition.

They are designed to combine features of both pellets and slugs. They have an aiming to offer the advantages of each design. Hybrid pellets typically have a solid front portion, similar to a slug for improved ballistic coefficient and aerodynamics.

The rear portion of the pellet is hollow, allowing it to engage with the rifling in the barrel like a Diabolo pellet. The combination of the solid and hollow sections in hybrid pellets aims to enhance accuracy, energy retention, and overall performance downrange. Hybrid pellets are available in various calibers and are used in air guns or air rifles capable of effectively shooting this specific type of ammunition.
