Exact Jumbo Heavy Diabolo | 5.5mm | 18.13gr | 500pcs | JSB

JSB Exact Jumbo Heavy Diabolo – heavy pellet for precision at longer distances

This air rifle ammunition from JSB combines a solid weight of 18.13 grains with a classic domed pellet shape in 5.5mm caliber. The heavier projectile is specially developed for shooters using powerful PCP air rifles from approximately 40 joules. The aerodynamic shape ensures a stable flight, allowing you to group consistently at distances of 75 to 100 metres. With 500 pieces per pack, you have ample ammunition to extensively test which velocity and energy deliver the best results with your specific air rifle.

Our experience from the Shogun team

The Exact Jumbo Heavy flies noticeably more stable than lighter alternatives, especially when shooting outdoors in changing wind conditions. The projectile retains its energy well over distance, resulting in predictable trajectories up to 75-100 metres. We find that these pellets perform best in air rifles that provide enough power to effectively accelerate the heavier weight. The Czech production quality of JSB guarantees consistent dimensions, which is reflected in tight groupings on the target.

Technical properties in practice

With a diameter of 5.5mm and a weight of 18.13 grains, this projectile belongs to the heavier class within the .22 segment. The domed shape provides a good balance between aerodynamics and stability at longer distances. The lead material is carefully selected and processed, resulting in a consistent weight per pellet. The packaging contains 500 pieces, more than enough to try out different distances and velocities. Using a chronograph helps you find the optimal balance between speed and precision for your specific setup.

Who is this air rifle pellet suitable for?

These precision pellets are designed for the experienced shooter working with a powerful PCP air rifle from 40 joules. The heavier weight requires sufficient energy to perform effectively, making them less suitable for lighter spring-powered or CO₂-powered systems. Shooters who regularly shoot at distances of 75-100 metres or participate in Field Target competitions appreciate the stability and predictability of this ammunition. Also for benchrest shooting, where every millimetre counts, these pellets prove their value through their consistent performance.
