Air rifles have long been associated with diabolo pellets, yet round balls, which are simply small spherical projectiles usually made of lead, remain an option for many shooters, including small game hunters under the right conditions.
Each projectile type has distinct characteristics that affect accuracy, performance, and suitability for different shooting styles. Understanding these differences helps shooters choose the right ammunition for their needs.
Pellets
Pellets are the modern standard for air rifles, largely because they are designed specifically for air-powered systems. Their waisted shape and hollow skirt allow the pellet to expand slightly when fired, sealing the bore and using compressed air efficiently. This design typically results in consistent velocities and good accuracy, especially at common air rifle distances.
Pellets are also widely available in many weights and shapes, such as wadcutters for target shooting or domed pellets for general-purpose use. For most shooters, pellets offer predictable performance with minimal experimentation.
Round balls
Round balls, by contrast, are a throwback to earlier airgun and firearm traditions. They are simple spheres, often undersized compared to the bore so they can be loaded easily. Because they lack a skirt to seal the bore, round balls may allow more air to escape around them, which can reduce efficiency and consistency in some air rifles.
However, in certain low-powered or smoothbore air guns, round balls can perform surprisingly well at short ranges. Their symmetry means they do not suffer from skirt deformation, which can be an issue with soft pellets during handling.
Accuracy is one of the biggest points of comparison. Pellets generally outperform round balls in rifled air gun barrels, as the rifling can grip the pellet skirt and impart stable spin. Round balls, having minimal contact with rifling, may not stabilize as effectively, leading to wider groups at longer distances. That said, at very close range, the difference may be less noticeable, particularly in informal plinking scenarios, or even when hunting squirrels and other small game at close range.
Cost and versatility also play a role. Round balls are often inexpensive and can sometimes be used in multiple platforms, including muzzleloaders and air guns of the same caliber.
Pellets, while slightly more specialized, offer greater consistency and are tailored to air rifle use.
Ultimately, pellets are the practical choice for most air rifle shooters seeking accuracy and reliability. Round balls, however, retain appeal for historical interest, experimentation, and casual shooting.
Choosing between them depends less on which is “better” and more on what kind of shooting experience one wants from an air rifle.
Don’t overlook round balls when planning an air gun hunt. Just get plenty of practice in, learn the limitations on round ball accuracy, then keep within those limits.
Any time I can do things a little differently with an air gun, I feel as if I’ve expanded my knowledge, as well as the enjoyment factor of shooting an air gun. Shooting round balls adds to that in a big way. As always, when it’s time for me to order air gun ammo, I do so at pyramydair.com.
