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.
Again these are packed in 150-count tins.
All the indications are that these new JSB Monster pellets are going to be in high demand. So you’ll need to get your orders in rapidly!

The post First Close Look At New JSB Monster Pellets appeared first on Hard Air Magazine.
2 pics of ammo that went through water jugs. The ones on the left are skirt end up (pellet &slug) Some crazy expansion!
) are a pellet that I will be using alot for 40Y and in hunting for sure! Smoked 2 gracks yesterday, the pop (read explosion!
) was insane. Use an old 4L washer fluid jug, fill with water, flip it bottom facing you, and no high expansion pellet will make it through. Heck the plastic bottle can simulate skin/fur/feather vs just a gel block.
The 'old' 15.89gr Hades don't have the same effect, dump speed fast and are too light in the first place. Excited to try the new Hades!
) The Ghost and myself got pretty wet and the pail survived! Now check the expansion on the new 25gr hades!! Huge win almost as good as the 25gr Ko slug. Picture has original Hades 15.89, 18gr Jsb, 25gr new Hades, Jsb KO 25gr slug, and a 25gr Mrd. Serious expansion @ 950fps!
) the slug barrel ever comes out. If Brk drags their a$$ long enough next year I may buy a dedicated slug gun. The HP definitely shoots them fast enough and expansion testing is always fun for a comparison! The 15.89 Hades and 18gr I shot on min so all the speeds going into the water were all within 50fps of each other. The new Hades I expect the most out of as they are only 150 in a tin but costed a few bucks more. For looks and expansion they are winners so far
40 yards (which is nothing for a 
) I was making my tiny mrd groups and I tossed 2 (I believe 23gr?) slugs in. One went left and a bit high second went dead on but 2 or so inches low so basically 2 fliers out of 2 shots. I stopped, popped in more mrds and watched it tighten right up again.
