The JSB Exact King Heavy MkII is a premium domed diabolo pellet in .25 calibre (6.35mm), weighing 33.95 grains and supplied in a pack of 300. Manufactured in the Czech Republic to JSB's famously tight tolerances, the MkII designation indicates a revised skirt geometry that improves feed reliability in rotary magazines without compromising the head-diameter control that makes these pellets so consistent. At 33.95 grains, this is a noticeably heavy .25 pellet — roughly a third heavier than a standard 25-grain load — giving it a ballistic coefficient of 0.046, strong energy retention at distance, and reduced susceptibility to wind drift. The domed profile delivers stable, predictable flight and good penetration on impact, making the King Heavy MkII a well-regarded choice for hunters targeting larger quarry at extended ranges as well as for serious air-rifle target shooters who need repeatable shot placement from a high-power PCP. Every pellet is checked to JSB's exacting quality-control standards before packing.
