Copper Plated Steel BB | 4.5mm | 1500pcs | JS

JS Copper Plated Steel BB – lightweight air rifle ammunition for recreational shooting

These round BBs from JS are specially developed for smoothbore air rifles suitable for BB ammunition in 4.5mm calibre. The relatively light weight of 0.33 grams makes them ideal for shooting at short distances up to approximately 10 metres. The copper coating over the steel core ensures less friction in the barrel, resulting in smoother feeding and consistent performance during recreational use.

Our experience from the Shogun team

We have found that these BBs perform particularly well in smoothbore air rifles specifically designed for this type of ammunition. The copper finish not only gives a premium appearance but also contributes to the durability of both the ammunition and your air rifle. During testing, it was noticeable that the domed shape provides predictable shooting behaviour, which is especially important when shooting at reactive targets or paper targets at short range.

Technical features in practice

With a calibre of 4.5mm and a weight of 0.33 grams per BB, these belong to the lighter category of air rifle ammunition. The steel core with copper coating offers the perfect balance between hardness and gliding properties. The practical bottle with a resealable cap contains 1500 pieces, which is sufficient for multiple shooting sessions. For optimal performance, we recommend using a chronograph to gain insight into the energy output of your specific air rifle with this ammunition.

Who is this air rifle ammunition suitable for?

These BBs are perfect for the recreational shooter who enjoys shooting at short distances at paper targets, cans, or spinners. They are particularly suitable for use in CO₂-powered air pistols and revolvers, as well as in pump-action air rifles designed for BB ammunition. The lightweight pellets make them ideal for indoor use or backyard shooting sports where energy must be kept limited. For shooters just starting out in the air rifle sport, these BBs offer an affordable way to practise extensively.
