JSB Knock Out HP Slugs – heavy slug for powerful PCP air rifles

The JSB Knock Out HP slugs in 6.35mm/.25 calibre with a weight of 33.49 grain are developed for shooters who want maximum energy transfer from their PCP air rifle. The hollow point design ensures controlled expansion upon impact, while the soft JSB lead guarantees stability. This slug for PCP air rifle is especially suitable for powerful air rifles with a minimum output of 40 joules to effectively shoot the heavy projectile.

Our experience from the Shogun team

When testing these Knock Out HP slugs, we immediately noticed the difference compared to traditional diabolo pellets. The aerodynamic shape and higher BC value of 0.092 provide excellent flight stability, even under varying weather conditions. The hollow point delivers impressive energy transfer upon impact. At distances up to 75 metres and beyond, these slugs maintain their trajectory, provided they are fired with sufficient power. The ideal projectile weight may vary per air rifle, with a chronograph offering valuable insight into the actual energy output of your setup.

Technical properties in practice

With 6.35mm/.25 calibre and 33.49 grain weight, these belong to the heavier air rifle ammunition in the JSB range. The hollow point pellet shape combines aerodynamics with expansion properties for maximum energy transfer. The soft lead from which these slugs are made ensures good sealing in the barrel and consistent velocities. The packaging contains 150 pieces, sufficient for extensive shooting sessions. The ballistic coefficient of 0.092 translates to less velocity loss over distance, making these slugs particularly suitable for PCP air rifles from 40 joules upwards.

Who is this air rifle slug suitable for?

These Knock Out HP slugs are ideal for experienced shooters with powerful PCP air rifles. Think of precision shooters participating in benchrest competitions or field target matches at longer distances. Due to the hollow point design and heavy weight, these slugs are suitable for pest control, although the use of air rifles for this purpose 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. Testing different grains pays off for optimal accuracy with your specific air rifle.
