The new JSB Exact Jumbo Monster Redesigned Deep 5.52mm 25.39gr 200PCS, for serious shooters that know what their rifle likes!

JSB went ahead and sorted their Monster Redesigned pellets into two variants: Deep and Shallow. The Deep has a deeper “cup” in the skirt, with the skirt itself being thinner. Meanwhile, the Shallow has a much shallower “cup” and a thicker skirt. Pro shooters always test all variants to see what their rifle likes best. Amazingly, some rifles love both and best grouping depends on the velocity the pellet travels at.

Specially designed for powerful air rifles. They are perfectly finished consistently, as per usual for JSB, which means the airgun pellets are highly accurate. The pellets have a dome head, so they’re very aerodynamic and they can be shot straight and far. This makes them excellent all-round pellets, which can be used for a variety of shooting activities. The weight of 25.39 grains, too, contributes to the straight and far flight of the JSB Jumbo Exact Monster Redesigned Deep airgun pellets with a diameter of 5.52 mm.

These JSB airgun pellets are packaged per 200 pcs.

According to JSB, the weight has been chosen to fit the most powerful air rifles currently available on the market. It is a really heavy weight pellets that is stable even at 50J+ power levels but fits also 70J+ rifles. Number one choice for the owners of FAC air guns. Muzzle velocity is 140 m/s if the power of airgun is set to 16J. Muzzle velocity is 250 m/s if the power of airgun is set to 50J. Muzzle velocity is 295 m/s if the power of airgun is set to 70J.

The new Monster editions are considerably heavier than the standard Jumbo pellets, designed to combine accuracy with high damage, always ensuring enhanced energy retention and impact with unmatchable accuracy for long distance shooting and pest control. A stable, true flight projectile for owners of the most powerful PCP air rifles.
