6.35 mm (.25) Airgun Ammunition

6.35 mm (.25) Airgun Ammunition: Built for Powerful PCP Air Rifles

6.35 mm (.25) has become one of the most popular calibres for modern PCP air rifles. Thanks to its heavier projectiles, this calibre delivers significantly more retained energy than 4.5 mm (.177) or 5.5 mm (.22) while maintaining outstanding accuracy. It is the preferred choice for many shooters looking to maximise the performance of their high-powered PCP air rifle, especially at medium and longer shooting distances.

At SEM Jacht & Schietsport you'll find an extensive selection of 6.35 mm (.25) airgun ammunition, including premium pellets and slugs from leading manufacturers. Whether you shoot for recreation, competition or long-range precision, our range includes the right ammunition for your air rifle.

Why choose 6.35 mm (.25)?

Over the past decade, the .25 calibre has established itself as one of the most popular choices for powerful PCP air rifles. The heavier projectile retains velocity and energy exceptionally well, offering excellent downrange performance while remaining highly accurate.

• More retained energy than 5.5 mm (.22).
• Excellent stability at medium and long distances.
• Wide choice of pellets and slugs.
• Designed for powerful PCP air rifles.
• Available in a broad range of projectile weights.

Which air rifles are available in 6.35 mm?

Most premium PCP manufacturers offer one or more air rifles chambered in .25 calibre.

• FX DRS, Impact, Crown, Maverick, Panthera and Dynamic.
• AirMaks Krait, Katran and Caiman.

These rifles are engineered to take full advantage of the increased energy and excellent ballistic characteristics offered by the .25 calibre.

Pellets or slugs?

The 6.35 mm calibre offers two main projectile types.

• Pellets remain the most versatile choice and deliver excellent accuracy in most .25 calibre air rifles.
• Slugs feature a higher ballistic coefficient (BC) and are intended for powerful PCP air rifles with sufficient power and the appropriate barrel specifications.

Many modern PCP platforms are specifically designed to stabilise slugs effectively. Always confirm that your air rifle is suitable before switching projectile types.

Projectile weight, BC and performance

Projectile weight is expressed in grains (gr) and plays an important role in determining muzzle velocity, retained energy and downrange performance. Heavier projectiles generally provide a higher ballistic coefficient (BC), helping them resist wind drift and retain velocity over longer distances.

Common weight ranges include:

• 25 to 27 grains.
• 30 to 34 grains.
• 34 to 40 grains.
• 40 to 50 grains.
• Heavy slugs exceeding 50 grains.

Every PCP air rifle has its own preferred projectile weight. Testing different weights often results in noticeably improved accuracy.

Yes. 6.35 mm and .25 calibre are simply two different measurements for exactly the same calibre.

Are slugs more accurate than pellets?

Not always. Slugs perform exceptionally well in powerful PCP air rifles designed for them, while pellets remain the preferred option for many air rifles.

Which projectile weights are most common?

Pellets are commonly available between approximately 25 and 34 grains, while slugs are available in weights exceeding 50 grains.

Can every .25 PCP air rifle shoot slugs?

No. Barrel design, twist rate, power output and rifle tuning all influence slug performance.

Why is .25 calibre so popular among PCP shooters?

It offers an excellent balance of power, retained energy, accuracy and projectile choice, making it one of the most versatile calibres for modern PCP air rifles.
