RPS Big Bore .582 – heavy slugs for powerful PCP systems

The RPS Big Bore .582 is designed for shooters who want to get the most out of their powerful PCP air rifle. With a projectile weight of 940 grains and a caliber of 14.78mm / .582, these slugs are among the heaviest air rifle ammunition available. This combination requires PCP systems from 300 joules upwards to fully utilise their potential. The Flat Nose (FN) projectile shape ensures maximum energy transfer on impact, making these slugs particularly effective at long range.

Our experience from the Shogun team

During testing, it was immediately noticeable how stable these heavy projectiles fly, even at distances beyond 100 metres. The mass of 940 grains keeps the projectile on course for longer and significantly reduces the influence of wind. The sound upon impact on steel targets is impressive – the kinetic energy is fully transferred thanks to the flat nose. For optimal results, we recommend a barrel with the correct twist rate to properly stabilise these heavy slugs.

Technical features in practice

The use of lead as a material provides the necessary mass and dimensional stability during flight. With 50 pieces per pack, you have enough ammunition for an extensive shooting session. The caliber of 14.78mm / .582 means your barrel must be specifically suited for this size – please check this in advance. The Flat Nose shape not only maximises energy transfer but also ensures a consistent shot pattern because the projectile reacts predictably during flight. Testing different loads with a chronograph helps you find the ideal velocity for your specific air rifle.

Who are these slugs suitable for?

These slugs are developed for experienced PCP shooters who have a powerful system of at least 300 joules. They excel at long distances where precision and impact are essential. Think of precision shooting at 150 metres and beyond, or situations where maximum energy transfer is desired. The heavy mass makes them less suitable for rapid follow-up shots, but for deliberate precision they are unrivalled in their class.
