JSB Knock Out Slugs – heavy slug for high-powered PCP air rifles

The JSB Knock Out is a 5.5mm slug weighing 25.39 grain with a hollow point design, specifically developed for powerful PCP air rifles. These heavy projectiles are made from soft lead and designed for maximum energy transfer upon impact. With a ballistic coefficient of 0.084, these slugs maintain their velocity and stability exceptionally well, making them suitable for precision shooting at distances of 75 to 100 metres in PCP systems from 40 Joules upwards.

Our experience from the Shogun team

In our tests, the JSB Knock Out slugs performed impressively in PCP air rifles with sufficient power. The heavy 25.39 grain projectile flies stably and predictably, even in light wind. The hollow point construction ensures excellent expansion upon impact, resulting in effective energy transfer. At distances between 75 and 100 metres, grouping remains consistent, provided your air rifle delivers enough power to keep these heavy slugs at speed.

Technical features in practice

With a calibre of 5.5mm and a weight of 25.39 grain, these slugs are on the heavier side for this calibre. The soft lead combined with the hollow point shape ensures reliable expansion. The packaging contains 200 pieces, which is sufficient for extensive testing sessions. The use of a chronograph is recommended to verify that your air rifle provides these heavy projectiles with the correct velocity for optimal performance at longer distances.

Who are these air rifle slugs suitable for?

These slugs are ideal for experienced shooters with powerful PCP air rifles seeking precision at distances of 75 to 100 metres. Thanks to the hollow point construction, they are also suitable for rat control and pest control, where we emphasise that the use of an air rifle is legally regulated. In many cases, an exemption or hunting licence is required, and this is only permitted for recognised pest controllers or certified users. For competition shooters engaging in long-range shooting, these slugs offer an excellent balance between weight, stability, and precision.
