The JSB Exact Monster is one of the heaviest diabolo pellets available in .177 calibre, weighing 13.43 grains (0.870g) with a 4.52mm head diameter. Designed specifically for the most powerful air rifles — including FAC-rated guns — the Monster's mass delivers high downrange energy and exceptional stability in wind, making it a sound choice for long-range field target shooting and airgun hunting where terminal performance matters. The domed round-head profile is characteristic of the Exact series: it seats consistently in the breech, promotes even air-seal engagement, and flies with the kind of repeatable accuracy that serious shooters expect from JSB. Every pellet in this 400-pack is individually hand-picked as part of JSB's quality-control process, rejecting any that fall outside tight tolerances for weight and dimension. The result is a tin with minimal shot-to-shot variation — important when a heavy, slower-moving pellet leaves less margin for inconsistency at distance. Suits FAC air rifles and other high-powered .177 platforms where lighter Exact weights fall short.
