The JSB Exact Jumbo RS 5.5mm pellets are the lightest-weight domed pellets in the JSB range, designed for shooters who demand high velocity and flat trajectories. The "RS" in their name stands for Rapid Speed, which refers to their ability to achieve higher velocities compared to regular pellets. The flat ballistic curve ensures a consistent trajectory, making them ideal for precision target shooting.
Crafted with the same match-grade quality that JSB is renowned for, these pellets are perfect for target shooters using sub-8 Joule air rifles or pistols. The aerodynamic dome shape further enhances their accuracy, making them one of the most reliable options for shooting enthusiasts.
Key Features:
- Rapid Speed: High velocity and a flat trajectory for excellent precision.
- Match-Grade Quality: Known for their consistency and accuracy, JSB Exact pellets are a top choice for competitive shooters.
- Domed Shape: The classic dome shape ensures superior aerodynamics, contributing to tighter shot groups.

Recommendation:
JSB Exact Jumbo RS 5.5mm pellets are a great choice for precision target shooting, especially for those using lower-powered air rifles and pistols. With their flat trajectory and high velocity, they are ideal for 10-meter competitions and general plinking. However, they are not suited for pest control or use in self-indexing magazines due to their larger contact area.
