Knock Out MKII | HP | 6.35mm | 33.49gr | 150pcs | JSB

JSB Knock Out MKII – heavy slugs for powerful PCP air rifles

The JSB Knock Out MKII combines a weight of 33.49 grain with a hollow point design in 6.35mm calibre. These heavy slugs are specifically developed for powerful PCP air rifles from 50 joules and above. The aerodynamic profile with the characteristic hollow point ensures stable flight paths at distances up to 75 metres and beyond, with maximum energy transfer on impact thanks to the hollow point design.

Our experience from the Shogun team

In our tests, these JSB slugs performed excellently in PCP systems with sufficient power. The MKII design shows improved flight stability compared to the previous generation, especially noticeable beyond 50 metres. The slugs maintain their grouping well, even in changing weather conditions. At distances around 75 metres, we observed consistent results, provided your air rifle delivers enough energy to keep these heavy projectiles at speed.

Technical features in practice

With a diameter of 6.37mm and a weight of 33.49 grain, this projectile requires a powerful air blast. The lead material in combination with the hollow point shape ensures optimal energy transfer. The packaging contains 150 pieces, sufficient for extensive shooting sessions. The ballistic coefficient of 0.093 indicates good aerodynamic properties for a hollow point projectile of this weight.

Who is this air rifle slug suitable for?

These slugs are ideal for experienced shooters with powerful PCP air rifles who seek precision at longer distances. The heavy weight and hollow point design make them suitable for pest control, where we emphasise that the use of an air rifle for control is legally regulated. In many cases, an exemption or hunting licence is required, and this is only permitted for recognised controllers or certified users. For recreational precision shooting at paper targets, these slugs are also excellently suited.
