Slug HP II | 6.35mm / .250 | 36gr | 120pcs | H&N

H&N Slug HP II 6.35mm 36gr – powerful slug for PCP air rifle at longer distances

The H&N Slug HP II is a cylindrical hollow point slug in caliber 6.35 mm / .25 with a weight of 36 grain. This air rifle ammunition is designed for PCP air pressure systems that deliver sufficient energy, with a recommended minimum of 40 Joule. Due to the hollow point design and the heavier projectile, this slug performs best at distances around 50 metres, where a stable flight and good energy transfer come together. The relatively favourable ballistic coefficient of 0.105 helps the projectile retain its velocity over that distance.

Our experience from the Shogun team

In our tests, the Slug HP II demonstrates calm and predictable flight behaviour once your PCP delivers sufficient energy. Around 50 metres, grouping remains consistent when your barrel and twist rate are well matched to this profile. The hollow point opening provides a clear energy transfer upon impact, making the slug interesting for those seeking consistent performance at that distance. Because slugs are sensitive to barrel twist, it is worthwhile to first shoot a few tins and assess the behaviour in your specific air rifle.

Technical properties in practice

With a caliber of 6.35 mm / .25, a weight of 36 grain and a head size of 6.35 mm, this projectile has sufficient mass to carry energy effectively up to around 50 metres. The hollow point design ensures good energy transfer upon impact, while the cylindrical profile and length of 8.3 mm contribute to stability in flight. The projectile is manufactured from lead, which ensures smooth passage through the barrel and good deformation upon impact. Each tin contains 120 pieces. Because performance depends on the energy output of your system, it is useful to test different grain weights and measure the actual energy with a chronograph; this gives you insight into whether you are at or above the recommended 40 Joule and allows you to fine-tune your accuracy.

Who is this air rifle slug suitable for?

This slug is intended for shooters with a powerful PCP system delivering a minimum of 40 Joule who wish to shoot accurately at distances around 50 metres. Precision enthusiasts and users of modern PCP air rifles with a suitable twist rate will get the most out of it. As this is a hollow point projectile with good energy transfer, it can also be used for pest and rodent control. Please bear in mind that the use of an air rifle for this purpose is legally regulated: in many cases, an exemption or hunting licence is required and it is exclusively permitted for certified pest controllers or authorised users.
