Steel BBs UMAREX 4.46 mm (4.5 mm calibre), 1500 pcs, threaded barrel compatible

Pack of 1500 UMAREX steel BBs with a nominal diameter of 4.46 mm designed to fit 4.5 mm calibre airguns with threaded barrels. Manufactured in Germany from stainless-steel material, the pack delivers a consistent pellet weight and shape for repeated target practice, plinking and training. The compact 35 g pack contains 1500 rounds and is compatible with a wide range of airguns that accept steel BBs in threaded-barrel configurations.

Advantages

UMAREX steel BBs are produced from stainless-steel for uniform hardness and corrosion resistance. The nominal 4.46 mm diameter ensures reliable feeding in 4.5 mm calibre magazines and loaders, while the smooth spherical shape supports consistent trajectories in short- to medium-range shooting. Threaded-barrel compatibility reduces the risk of jamming in models that require or support BBs for threaded barrels. The small, lightweight packaging makes storage and transport convenient for range sessions.

Suitable for

• Target shooting at short and medium distances
• Plinking and informal recreational shooting
• Training and skill practice for airgun users
• Use with 4.5 mm calibre airguns that accept steel BBs and threaded-barrel feeding

How to use

Verify that your airgun is rated for steel BBs and supports use of threaded-barrel feeding before loading. Load BBs into the magazine, reservoir or feed mechanism according to the firearm manufacturer's instructions. Use appropriate eye and ear protection and follow standard safety procedures at all times. Maintain the feed path and barrel by removing debris and checking for any signs of wear that might affect feeding or accuracy.

Recommendations

For best results, store the pack in a dry place to preserve the stainless-steel finish and avoid mixing with other shot sizes. Use these BBs for recreational shooting and target practice; do not use in firearms not rated for steel BBs. Regularly inspect the gun's feed system and barrel when switching ammunition types to ensure safe and reliable operation.
