7.62 mm caliber pellets for compressed air rifles

7.62 mm (.30) Pellets and Slugs for PCP Air Rifles

7.62 mm (.30) pellets sit at the larger end of the mainstream airgun calibre range and are particularly associated with PCP air rifles designed to use substantially heavier projectiles than those normally found in .177, .22 or .25 calibre.

In this CARBIN category you will find .30 calibre airgun ammunition based on two distinct projectile concepts: traditional Diabolo pellets and .30 calibre slugs. Although they share the same nominal calibre, their shape, weight, length and behaviour in the barrel can be very different.

The current range includes JSB Exact .30, JSB KnockOut .30, Spoton Monster .30 and Diana Domed XXL .30. If you are looking for other calibres, weights or pellet shapes, you can also explore our complete range of airgun pellets.

What calibre is 7.62 mm in an air rifle?

In airguns, 7.62 mm corresponds approximately to .30 calibre. This is why the same projectile diameter may be described commercially as 7.62 mm, .30 or .30 calibre.

In this context, the figure refers to the nominal projectile diameter. It should not automatically be confused with the designation of a firearm cartridge.

.30 calibre allows PCP platforms to use considerably heavier projectiles than smaller airgun calibres. However, a larger diameter or heavier projectile does not automatically mean greater accuracy or a flatter trajectory. Performance also depends on projectile geometry, ballistic coefficient, velocity and, above all, how well the ammunition matches the barrel and configuration of the rifle.

7.62 mm (.30) Pellets and Slugs Compared by Weight

Projectile weight in grains is one of the most useful figures when comparing .30 calibre airgun ammunition. Two projectiles with the same nominal diameter may have different mass, length and geometry and therefore behave differently in the same PCP air rifle.

For reference, 1 grain is approximately 0.0648 grams.

This comparison highlights an important point: two projectiles can weigh exactly 50.15 grains and still have completely different geometries. The JSB Exact uses a traditional Diabolo design, while the JSB KnockOut is a slug.

Projectile weight should therefore never be considered in isolation. The combination of weight + geometry + projectile length + barrel provides much more useful information than simply choosing the heaviest option.

.30 Pellets vs .30 Slugs: What Is the Difference?

A traditional Diabolo pellet and an airgun slug can both be .30 calibre, but they are two fundamentally different projectile designs.

A slug is not automatically more accurate than a Diabolo pellet. The most suitable projectile is the one that is compatible with the rifle and delivers consistent groups through its particular barrel.

JSB Exact 7.62 mm: .30 Calibre Diabolo Pellets

The JSB Exact 7.62 mm uses the familiar Diabolo profile of the Exact family, with a rounded head, narrow waist and skirt.

CARBIN currently offers this reference in 44.75 grains / 2.90 g and 50.15 grains / 3.25 g. This creates an especially useful comparison because the projectile concept remains similar while the mass changes.

JSB KnockOut .30: 50.15 Grain Airgun Slug

The JSB KnockOut .30 follows a very different design philosophy from the Exact. It is a 50.15 grain / 3.25 g Hollow Point slug with a more cylindrical profile.

The comparison with the 50.15 grain JSB Exact is particularly useful: both have the same nominal weight, yet their shape is fundamentally different.

This demonstrates why grains alone cannot tell you which .30 projectile will perform best in a particular PCP air rifle.

Diana Domed XXL .30: 49 Grain Heavy Pellet

The Diana Domed XXL 7.62 mm adds another useful reference point to the current range. It weighs 49 grains / 3.15 g and uses a domed pellet profile.

Its weight sits between the lighter 44.75–45 grain options and the 50.15 grain JSB variants, making it particularly useful when comparing how different projectile masses behave within the same calibre.

Spoton Monster .30: 45 Grain Pellet

The Spoton Monster 7.62 mm weighs approximately 45 grains / 2.92 g.

Its mass is extremely close to that of the 44.75 grain JSB Exact, creating another useful comparison: similar projectile weight, but a different manufacturer and potentially different dimensions and behaviour in a particular barrel.

Which .30 Pellet Weight Should You Choose?

There is no universally ideal pellet weight for every .30 calibre PCP air rifle.

The current CARBIN range includes projectiles from approximately 44.75 to 50.15 grains. Even within this relatively narrow window there is a noticeable difference in projectile mass.

When comparing 7.62 mm ammunition, consider:

• Projectile weight in grains.
• Diabolo or slug geometry.
• Projectile length.
• Magazine compatibility.
• Barrel compatibility.
• The groups actually produced by your rifle.

A 50.15 grain projectile is not automatically more accurate than a 44.75 grain pellet. Accuracy depends on the complete interaction between the projectile and the PCP platform.

Which Air Rifles Use 7.62 mm (.30) Pellets?

.30 calibre is particularly associated with PCP air rifles. Pre-Charged Pneumatic technology allows manufacturers to develop platforms capable of working with heavier projectiles and larger airgun calibres.

CARBIN's PCP range includes rifles offered in 7.62 mm / .30 calibre. Always check the exact rifle variant before selecting ammunition, as the same model family may be sold in several different calibres.

FX Airguns PCP Rifles in .30 Calibre

FX Airguns is one of the manufacturers with a strong presence in the larger-calibre PCP market. Our range of FX Airguns PCP air rifles includes platforms and variants available in 7.62 mm / .30 calibre.

Advanced FX platforms are particularly relevant when discussing pellets and slugs because different projectile geometries, weights and barrel configurations can produce noticeably different results.

7.62 mm vs 6.35 mm, 5.5 mm and 4.5 mm Airgun Calibres

7.62 mm sits at the larger end of the commonly available airgun calibres. A larger calibre, however, is not automatically the right choice for every shooter or every PCP platform.

Will Any .30 Pellet Work in Any 7.62 mm PCP Air Rifle?

Not necessarily. Sharing the same nominal calibre is a basic requirement, but it does not guarantee that every projectile will behave in the same way.

Projectile weight, length and geometry, together with the characteristics of the barrel, can affect both compatibility and grouping. With slugs, it is particularly important to consider whether the projectile length and profile are suitable for the rifle's magazine and barrel system.

Start with the rifle manufacturer's specifications, then compare compatible ammunition to determine which projectile produces the most consistent results in your particular PCP.

How to Compare .30 Pellets and Slugs in the Same PCP

When comparing ammunition, keep the distance, rest and shooting conditions as consistent as possible. This makes it easier to determine whether differences in grouping are related to the projectile rather than changing test conditions.

The current range allows several particularly useful comparisons:

• 44.75 gr vs 50.15 gr JSB Exact: similar pellet concept, different projectile weight.
• JSB Exact 50.15 gr vs JSB KnockOut 50.15 gr: identical nominal weight, fundamentally different geometry.
• JSB Exact 44.75 gr vs Spoton Monster 45 gr: almost identical weight, different manufacturers.
• Diana Domed XXL 49 gr vs JSB Exact 50.15 gr: similar heavy-pellet range, different brands and projectile designs.

These comparisons help separate three variables that are often confused: weight, projectile geometry and manufacturer.

Frequently Asked Questions About 7.62 mm (.30) Pellets

Are 7.62 mm and .30 calibre the same in airguns?

Yes. In the airgun context, 7.62 mm corresponds approximately to .30 inch, so both designations are commonly used for this projectile diameter.

How much does a .30 calibre airgun pellet weigh?

It depends on the reference. The current range includes examples at 44.75 grains, 45 grains, 49 grains and 50.15 grains, equivalent to approximately 2.90 to 3.25 grams.

What is the difference between a .30 pellet and a .30 slug?

A traditional pellet normally uses a Diabolo shape with a head, narrow waist and skirt. A slug has a more cylindrical profile. Both can be .30 calibre, but they can behave very differently in the same barrel.

What is the difference between JSB Exact and JSB KnockOut?

The JSB Exact is a Diabolo pellet, while the JSB KnockOut is an airgun slug. The 50.15 grain versions provide a particularly useful comparison because the nominal weight is the same but the projectile geometry is different.

How heavy is the Diana Domed XXL .30?

The Diana Domed XXL 7.62 mm weighs 49 grains / 3.15 grams.

How heavy is the Spoton Monster .30?

The Spoton Monster 7.62 mm weighs approximately 45 grains / 2.92 grams.

Are .30 calibre pellets mainly used in PCP air rifles?

Yes. .30 calibre is particularly associated with PCP air rifles designed to work with heavier projectiles and larger airgun calibres.

Is a heavier .30 pellet always more accurate?

No. Weight is only one factor. Accuracy also depends on projectile geometry, velocity, barrel characteristics and how well the ammunition matches the individual rifle.

Is a .30 slug better than a .30 Diabolo pellet?

Not necessarily. They are different projectile concepts. The better option is the compatible projectile that produces the most consistent grouping in the particular PCP air rifle.
