Copper Plated Steel BB – 4.5mm airgun ammunition for smoothbore shooting

These JS round pellets are designed for smoothbore airguns chambered in 4.5mm calibre BB ammunition. The 0.33 gram weight makes them suitable for short-range target shooting up to 10 metres. The copper coating over the steel core reduces barrel friction for consistent feeding and performance.

Construction and materials

Each BB features a steel core with copper plating, combining durability with smooth bore passage. The domed shape provides predictable flight characteristics. Packaged in a resealable container holding 1500 pieces, the copper finish offers both functional benefits and corrosion resistance.

Application and use

Designed for smoothbore air rifles, these BBs excel in CO2 pistols, revolvers, and pump-action airguns. The light 0.33 gram weight suits indoor ranges and backyard plinking where energy output must remain limited. Ideal for paper targets, tin cans, and reactive spinners at close range.

Integration and compatibility

These BBs are compatible with any 4.5mm/.177 calibre smoothbore airgun designed for steel BB ammunition. Not suitable for rifled barrels or pellet-only airguns. The copper plating ensures smooth magazine feeding in repeating airguns and reduces wear on brass components.
