JSB Jumbo Heavy .22 | 500 pcs | 18.13 gr
Pellet-on-Pellet Accuracy. Built for Serious Shooters.
The JSB Match Diabolo Exact Jumbo Heavy is one of the most trusted .22 caliber pellets in the airgun world — and for good reason. At 18.13 grains, this heavy domed pellet delivers the downrange energy and flight stability that hunters, pest controllers, and long-range target shooters rely on. With countless shooters reporting pellet-on-pellet groups at 40 yards, the Exact Jumbo Heavy isn't just a pellet — it's a performance standard.
Overview
JSB's manufacturing precision is legendary, and the Exact Jumbo Heavy showcases exactly why. The domed profile enhances aerodynamics for a stable, consistent flight path, while the heavier 18.13gr weight provides deep penetration and reliable energy transfer on impact — making it equally at home on small game, pest control, and precision target work. Each 500-count tin gives you an extended supply of pellets held to JSB's famously tight tolerances.
