First Close Look At New JSB Monster Pellets

Back in December 2023, HAM readers first heard about the new JSB Monster pellets. Now they are shipping and we can take a close look at the new Monsters in real life!

“Monster”, is a designator for JSB pellets which are heavier than “Heavy”. You can see the Hard Air Magazine guide to JSB pellet names here for more details. 

In fact, we have received samples of four new JSB Monster pellets. These are as follows:

– 25.39 Grain Jumbo Monster Redesigned Shallow
– 25.39 Grain Jumbo Monster Redesigned Deep
– 28.55 Grain Jumbo Monster Grand
– 25.39 Grain Hades Monster .22

Note that the Hades pellets have a 5.50 mm head diameter, indicated by this label on the bottom of the tin.

The Jumbo Monsters have a head diameter specification of 5.52 mm, as we can see here.

Now let’s look at each of these new JSB Monster pellets in more detail…


25.39 Grain Jumbo Monster Redesigned Shallow

The Redesigned, shallow skirt JSB Jumbo Monsters are the same as current production.

They are available in 200-count and 350-count tins.

The photograph below shows the shallow skirt implementation.

25.39 Grain Jumbo Monster Redesigned Deep

The Redesigned Deep Skirt JSB Jumbo Monsters are a return to the original “Redesigned” pattern, with deep, thin skirts. That’s easily seen from the photograph below.

Again, they will be available in 200- and 350-count tins.


28.55 Grain Jumbo Monster Grand

These “heavier than heavy” Monsters are a new introduction and are clearly designed to keep pace with the ever-increasing power levels of .22 caliber PCP air rifles.

These are available in 150 count tins.

25.39 Grain Hades Monster .22

The 25.39 Grain Hades Monsters are a new model with a longer skirt than the existing 15.89 Grain 5.5 mm Hades pellets.
