The JSB Exact Heavy Diabolo .177 Cal pellets are designed for shooters who demand superior accuracy, consistent flight, and reliable long-range performance from their air rifles. Manufactured by JSB Match in the Czech Republic, these premium pellets feature a 10.34-grain weight and domed (round-nose) design, which helps improve stability and maintain velocity during flight. This aerodynamic shape reduces air resistance and allows the pellet to deliver tighter groupings, especially at longer shooting distances.

Each pellet is produced with strict quality control to ensure uniform weight, precise dimensions, and balanced construction, resulting in consistent performance shot after shot. The heavier design also provides better wind resistance and stronger downrange energy, making it suitable for powerful spring-piston and PCP air rifles.

Typically packed in tins of 500 pellets, the JSB Exact Heavy Diabolo .177 Cal is widely trusted by target shooters and field-target competitors who require dependable ammunition for practice and competition. With its excellent aerodynamics and precision manufacturing, this pellet delivers reliable accuracy and smooth shooting performance for serious airgun enthusiasts.
