- Exact RS is the lightest JSB pellet with a rounded Round head, designed for precision shooting. This ultra-fast, oversized 4.52 mm precision pellet features a very flat trajectory and minimal drop, ensuring exceptional accuracy and stability.

Diabolo Exact 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.
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 = 255 m/s for rifles with 16–17 J of energy. Ballistic Coefficient (BC): 0.015 ensures a very flat trajectory at short and medium distances, although it may be more affected by wind at very long ranges.
Features that distinguish the Exact series of pellets are high quality, precision manufacturing, and perfect balance. These contribute to maximum accuracy when shooting at long distances. Accuracy results from a stable, flat trajectory and minimal ammunition drop at long distances, which the diabolo owes to its rounded head that reduces air resistance. The pellet is characterized by excellent grouping in all conditions, even in gusty winds.
