JSB Match Diabolo is a Czech brand manufacturing top-tier airgun pellets and ammunition, recognized by competitive shooters, hunters, and enthusiasts worldwide as one of the gold standards in precision airgun ammunition. The company was founded in 1991 by Josef Schulz — a former competitive shooter and shooting sports coach from Bohumín, Czech Republic — who set out to apply his expertise in precision shooting to developing a new generation of airgun ammunition. The initials JSB are no coincidence: they stand for Josef Schulz Bohumín. Since then, the company has revolutionized the airgun pellet market and become the supplier of choice for Olympic teams, professional field target competitors, and leading airgun manufacturers.
History and Quality Philosophy
After retiring from competitive shooting and coaching, Josef Schulz dedicated himself to the research and development of precision airgun ammunition. Under Schulz's project, pellets were produced at his own initiative, using his own tooling and production equipment — giving the brand a distinctly technical and quality-driven character from the very beginning, rather than a purely commercial one. In 2008, JSB Match Diabolo a.s. acquired Schulz's operation and restructured it as a joint-stock company, preserving the continuity of its quality philosophy and manufacturing methods. Today, the Bohumín facility produces no fewer than 65 million pellets per month — each one inspected by one of nearly forty qualified quality controllers. The company manufactures and calibrates its own dies and stamping machinery, ensuring absolute control over every production parameter, from lead alloy composition to the weight tolerance of the finished projectile.
Technology and Quality Control
JSB pellets are produced from 99.97% pure lead and subject to rigorous weight control with a tolerance of ±0.001 g — a specification unattainable in lower-grade mass production. Every production batch is ballistically tested before being cleared for sale. A unique batch identification code is printed on the bottom of each tin, enabling full lot traceability. JSB manufactures pellets not only under its own brand but also on contract for leading airgun manufacturers — including FX and Daystate — who entrust the company with producing ammunition sold under their own labels. The exceptional accuracy of JSB Exact (Diabolo series) pellets means that many airguns deliver tighter groups with JSB than with ammunition from other manufacturers.
Product Lines
JSB's flagship line is the Exact Diabolo — a domed precision pellet available in several calibers (.177/4.5mm, .22/5.5mm, .25/6.35mm, and .30/7.62mm) and various weights, designed primarily for Field Target competition and precision hunting. The Hades series features expanding pellets with a precisely engineered jaw-shaped hollow point head, delivering increased energy transfer with minimal downrange loss. The Monster series comprises heavyweight, high-grain pellets with a longer profile suited to slower PCP airguns. JSB Predator Polymag is an innovative expanding ammunition developed in partnership with an American patent holder for the technology. Sampler packs containing several pellet variants are also available — ideal for shooters looking to find the optimal ammunition for their airgun.
