The JSB Exact Jumbo Heavy is a domed diabolo pellet in .22 calibre (5.52mm head), weighing 18.13 grains — noticeably heavier than the standard Exact Jumbo. That extra mass is its defining advantage: at range, the Jumbo Heavy retains more energy and resists wind deflection better than lighter rounds, making it a sound choice for field target shooting, hunting and pest control where shots may extend beyond typical garden ranges. The 5.52mm head diameter ensures a firm bore fit in any standard .22 air rifle barrel, which promotes consistent pellet engagement and tight groups. Like all JSB Exact pellets, every one in this 250-count tin passes through hand-picked quality control at the Czech factory, so weight consistency and head-diameter uniformity are tightly maintained. Best suited to higher-powered .22 air rifles that can make full use of the pellet's mass, the Jumbo Heavy is a trusted choice for UK air-rifle hunters and pest controllers who need reliable performance at distance.
