JSB Exact Jumbo RS 5.52 mm pellets, 250 pcs (546207-250)

Diabolo Exact Jumbo RS is the lightest JSB pellet with a rounded head. The abbreviation RS (Rapid Speed) denotes an ultra-fast pellet with a very flat trajectory, designed for precise shooting. The rounded head reduces air resistance, resulting in a flat trajectory and minimal drop. The RS name also refers to the automotive industry, where Rally Sport (RS) is used for lightweight yet powerful sporty car versions. Packaging 250 pcs.

Precise and carefully selected – a very light and fast pellet, ideal for precision shooting. Despite its low weight, it achieves a much higher velocity compared to other Exact pellets, behaving like its heavier counterparts. The muzzle velocity is vo = 192 m/s for rifles with 16–17 J of energy. Ballistic Coefficient (BC): 0.026 ensures a very flat trajectory at short and medium distances, although it may be more affected by wind at very long ranges.

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.
