The “heavier than heavy” JSB Exact Jumbo Monster Grand 5.52mm 28.55gr 150PCS,  clearly designed to keep pace with the ever-increasing power levels of .22 calibre PCP air rifles.

Somewhat heavier than the traditional Jumbo Monsters familiar to so many PCP air rifle shooters, now designed to bridge the gap from the JSB Monster pellets for those looking for a heavier weight. Specially crafted for high power air rifles, designed with a dome-head diabolo shape and perfect centre of gravity distribution, contributing to stability, down-range ballistics and providing a highly accurate, long distance shooting projectile for owners of powerful FAC weapons. Especially for benchrest shooters.

These Jumbo Monster Grand pellets are manufactured in .22 caliber. The Czech firm has taken the opportunity to introduce a new 28.55 Grain version of the Jumbo Monster.

That makes them somewhat heavier than the traditional 25.39 Grain Jumbo Monsters that are familiar to so many PCP air rifle shooters. So, they bridge the gap from the Jumbo Monsters pellets and the extremely heavy Beast pellets. Now the heaviest of Exact Jumbo pellets offered by JSB.



Calibre: 5.5mm (.22)
Diameter: 5.52mm
Grain Weight: 28.55
Gram Weight: 1.850
