The JSB Exact Jumbo Monster is a heavyweight domed airgun pellet built for high-powered and FAC-rated .22 air rifles. At 25.39 grains and 5.52mm head diameter, this is one of the heaviest pellets in the JSB Exact range — designed specifically for rifles generating 16 joules or more, with optimal performance at 50J and above. The extra mass trades muzzle velocity for outstanding downrange energy retention and resistance to wind drift, making the Monster a practical choice for longer shots in open country where a lighter pellet would stray. The round-nose domed profile produces a stable, predictable arc, and JSB's rigorous hand-picking quality-control process on the Exact series ensures every pellet in the tin meets strict tolerances for head diameter and weight consistency. JSB tested accuracy at 45 metres — five shots must group with centres within 16mm — so the quality threshold is measurable rather than merely claimed. Supplied in a tin of 200, these pellets are not suitable for sub-12ft·lb rifles or standard pellet magazines due to their length and weight.
