JSB Match Diabolo Pellets - Precision for Champions
Since 1991, the Czech brand JSB Match Diabolo has combined a passion for shooting with engineering precision. Founded by shooter and coach Josef Schulz, the company is built on first-hand experience. Its use of unique technologies and manual selection has earned JSB a reputation for producing some of the most accurate pellets in the world. Top competitors confirm the quality—JSB exports 90% of its production to over 30 countries. The catalog includes more than 200 pellet variants, featuring different shapes, weights, and calibers, all precisely calibrated and compliant with strict standards. Choose wisely and shoot precisely—JSB stands for precision, passion, and innovation.
JSB PREMIUM
The Premium series represents the pinnacle of JSB’s offering: each pellet is hand-picked from the best production batches, weight-sorted with a tolerance of ±0.001 g, and individually packed to ensure it arrives in perfect condition. This meticulous quality control guarantees exceptional consistency and flight stability - qualities appreciated by top competitors in ISSF events. The lineup includes Match Premium (Light, Middle, Heavy), Exact Premium, and Exact Express Premium, allowing shooters to match pellet weight to their specific airgun for both competition and recreational precision shooting.
JSB MATCH
The Match series is a true JSB classic, with roots going back to 1991 when the first flat-head pellets began dominating competitions. Exceptional manufacturing precision and rigorous quality control ensure each pellet punches a perfectly round hole in the target at 10 meters. Available in Light, Middle, and Heavy versions, shooters can match the weight to their specific gun. Although designed for competitive use, these pellets are also ideal for dry-fire biathlon practice and casual target shooting at 15 meters.
JSB EXACT .177
Exact .177 (4.5 mm) is the gold standard for precision in the Field Target world. Carefully balanced weight, purpose-built shape, and perfect center of gravity result in stable flight even in crosswinds. Each batch is manually inspected, and the wide range of diameters and weights allows for perfect barrel matching. It's no surprise that over 90% of Field Target and Hunter Field Target competitors choose JSB. Factory tests at 45 m show an average grouping of just 12 mm—translating to outstanding results even at 25 m for recreational use.
JSB EXACT JUMBO .22
Exact Jumbo in .22 caliber (5.5 mm) dispels the myth of "inaccurate" diabolo pellets in this size—shooters consistently hit small targets at 50 m, and many use it effectively at even greater distances. Available in Express, Heavy, RS, Monster, and Beast variants, it lets users match pellet weight to airgun power. Thanks to its refined profile and round head, it delivers tight grouping and high energy retention, making it ideal for outdoor training at 50–60 m and long-range plinking.
JSB EXACT KING .25
Exact King was JSB’s first pellet in .25 caliber (6.35 mm). Meticulously engineered and subjected to strict quality control, it offers outstanding accuracy. Its mid-range weight suits most PCP rifles in this caliber. Requiring energy above 16 J, it’s used with permits in some countries but often replaces firearms in hunting and sport shooting abroad. King excels in fast-paced events like steel challenge and delivers pinpoint accuracy in training at 60–90 m.
JSB EXACT .20 · .30 · .35
JSB also offers intermediate and heavy calibers. Exact .20 (5 mm) balances .177 precision with .22 power—perfect for those wanting a flatter trajectory with higher energy. The .30 (7.62 mm) was the first mass-produced pellet in its size, developed with hunting airgun manufacturers. Weighing approx. 2.9 g, it delivers impressive accuracy. The mighty Exact .35 (9 mm) is the largest pellet caliber on the market - at 5.2 g, it generates enormous energy while maintaining a flat trajectory, ideal for legal hunting. These caliber options enable family shooting competitions at different distances and allow perfect ammo pairing with any air rifle.

JSB HADES
The Hades line was designed with hunters in mind but also delivers tons of fun for recreational shooting. Based on the popular Exact King Heavy series, Hades pellets are highly accurate and work reliably across various barrels and muzzle velocities. The specially shaped head features deep notches that deform easily on impact, maximizing energy transfer while minimizing pass-through. This makes them effective for small game hunting (where legal) and visually dramatic for plinking, delivering a satisfying “blink & pop” without damaging surroundings.
JSB STRATON
Straton pellets feature a sharp, pointed head designed for maximum penetration. JSB invites you to unleash your inner hunter - this shape ensures punch-through performance on harder targets like clay pigeons, metal squirrels, or wooden rats. Versatile .177 and .22 versions fit most air rifles and, at 16 J energy, reach around 240 m/s, offering a flat trajectory and dependable accuracy. Straton is perfect for backyard ranges—both for dynamic and precision shooting disciplines.
JSB PREDATOR POLYMAG
The unique Predator Polymag combines traditional diabolo design with cutting-edge technology. Developed with a U.S. partner, this pellet features a patented two-part construction: a hollow point lead body with a sharp polymer tip. This combination delivers exceptional penetration and expansion while maintaining accuracy—making Polymag a favorite among hunters. For recreational use, the polymer tip provides dramatic “explosions” on metal or rubber targets, making it an excellent choice for challenging reactive shooting.
JSB SLUG
JSB Slugs are heavy, solid projectiles with a high ballistic coefficient. Unlike traditional diabolo shapes, their bullet-like design reduces drag, resists wind, and enables a flatter trajectory. Designed for high-power airguns—especially PCP - they are perfect for long-range shooting. The .177 KnockOut versions range from 0.65 g to 0.87 g, with heavier options available in larger calibers. With these slugs, long-range plinking beyond 75 m becomes a thrilling experience, and their flight stability is appreciated even in extreme-distance rifle testing.
