4.4 mm (.173) Airgun Ammunition for Classic Air Rifles

4.4 mm (.173) round balls are among the oldest types of airgun ammunition still in production today. Although this calibre has largely been replaced by the more common 4.5 mm (.177), it continues to be used in classic air rifles and modern reproductions of traditional gallery rifles. At SEM Jacht & Schietsport you'll find quality 4.4 mm lead round balls for these specialised airguns.

This ammunition is specifically manufactured for airguns designed to shoot 4.4 mm lead round balls. Always use the calibre recommended by the manufacturer of your airgun.

A calibre with a long tradition

The 4.4 mm (.173) calibre has a rich history dating back to the late nineteenth century. During the early development of air rifles, lead round balls were widely used because they were simple to manufacture, reliable and easy to load.

For many decades these rifles were a familiar sight at shooting galleries, fairs and traditional festivals throughout Europe. Today that heritage continues with modern air rifles such as the DIANA Oktoberfest Rifle, which is inspired by the classic gallery rifles and still fires 4.4 mm lead round balls.

Why 4.4 mm instead of 4.5 mm?

Although the difference is only 0.1 mm, 4.4 mm and 4.5 mm are completely different calibres.

• 4.4 mm uses lead round balls.
• 4.5 mm (.177) generally uses pellets or slugs.
• The projectiles are not interchangeable.
• Always use the calibre specified by the manufacturer.

The barrel dimensions and loading system are designed specifically for 4.4 mm round balls, making them unsuitable for standard .177 pellets.

Lead round balls: simple, reliable and proven

Unlike modern pellets, 4.4 mm ammunition consists of perfectly round lead balls. This traditional design has been successfully used for well over a century and remains popular among collectors and enthusiasts of classic air rifles.

The round balls are manufactured to consistent dimensions to ensure reliable feeding and dependable performance in airguns designed for this calibre.

Which airguns use 4.4 mm ammunition?

4.4 mm (.173) lead round balls should only be used in airguns specifically chambered for this calibre.

• DIANA Oktoberfest Rifle
• Traditional gallery rifles
• Classic air rifles designed for lead round balls

If you are unsure which calibre your airgun requires, always check the markings on the rifle or consult the manufacturer's manual before purchasing ammunition.

Weight and material

Most 4.4 mm ammunition consists of lead round balls. Depending on the manufacturer, the projectile weight may vary slightly, but every product is designed for reliable performance in compatible airguns.

The simple spherical design makes these projectiles easy to load and ideal for recreational target shooting with traditional air rifles.
