Exact Jumbo Monster | 5.5mm | 25.39gr | 200pcs | JSB

JSB Exact Jumbo Monster – heavy pellets for powerful PCP air rifles

The JSB Exact Jumbo Monster pellets, with their 25.39 grain weight and 5.5mm caliber, are designed for shooters who want to maximise energy. These domed projectiles perform best in PCP air rifles from 40 joules upwards, where they can fully demonstrate their stability and penetration power. The heavier weight makes them ideal for precision shooting at medium to long ranges, with the aerodynamic shape ensuring a stable flight.

Our experience from the Shogun team

In our tests, these Monster pellets perform exceptionally well in powerful PCP systems. The domed shape provides excellent ballistics, especially noticeable beyond 50 metres where lighter projectiles lose stability. The high weight of 25.39 grain keeps the velocity subsonic in most setups, which benefits precision. We see consistent groupings at distances between 75 and 100 metres, depending on your air rifle and shooting skills.

Technical features in practice

With a caliber of 5.5mm and a weight of 25.39 grain, these pellets are built for impact. The lead material ensures the right mass distribution and deformation characteristics. The domed pellet shape offers the best balance between aerodynamics and energy transfer. Each pack contains 200 pieces, enough to test different distances and settings. JSB is known for their consistent production, resulting in uniform weights and dimensions per projectile.
