JSB Exact Jumbo 5.51 mm pellets, 500 pcs (546246-500)

Diabolo Exact Jumbo is the most popular over-caliber pellet model from JSB with a Rounded head in 5.51 mm caliber. Its stable flight path results from a higher weight and perfectly positioned center of gravity, ensuring exceptional accuracy even at long distances. This pellet is widely used by shooters, including world champions in FT and HFT competitions, achieving medal-winning results at international events. The smooth pellet cup, without knurling, minimizes air resistance and increases shooting precision.

Precise and hand-selected - it is ideal for accurate long-range shooting and competitive use, such as Field Target (FT) and Hunter Field Target (HFT), competitions, ensuring excellent grouping. Muzzle velocity vo = 175 m/s is optimized for air rifles with 16 J energy. The optimal Ballistic Coefficient (BC) of 0.028, combined with proper weight and shape, ensures a flat trajectory and minimal dispersion.

Exact Jumbo .22 - if you’ve ever heard claims about the alleged inaccuracy of 5.5 mm Diabolo pellets, it’s worth verifying them in practice. Just take a look at the achievements of shooters hitting small targets at distances reaching up to 200 meters. Can the central dispersion of 19 mm in 102 yards (approx. 90 meters) really be considered inaccurate? Definitely not — especially given that we’re talking about air rifles. When paired with the right rifle, Exact Jumbo .22 pellets can deliver accuracy that will surprise even the most skeptical shooters. Thanks to their optimal weight, specially engineered shape, and perfectly balanced center of gravity, Exact Jumbo pellets are an excellent choice for long-range shooting. The Exact Jumbo series, like all JSB products, undergoes a strict, manual quality-control process at the final stage of production, ensuring top-tier ammunition quality — the rest of the success is in the shooter’s hands.
