Slightly lightened and therefore significantly faster Exact Jumbo variation. The JSB Diablo Exact Jumbo Express Pellet is a unique choice for weapons with restricted power. For those who prefer flatter trajectory and higher speed. But the Exact Jumbo Express pellets are not sill too light to fly away in the wind.

I really like these pellets

By TimothyUSADecember 11, 2018

Very clean and accurate

By ChengUSAJune 15, 2018 Verified Purchase

JSB Diabolo pallets tend to get crush a lot because the thin and soft skirts so have to sort them out.The good and/or undamaged one shoot good no doubt about it.I think the manufacturer and/or dealer should find a way to ensure the safety of their quality products.Every time I ordered this JSB pallets I have to sort them out the good one and lost between 50 and 100.My Benjamin Marauder Pistol like these 14.3 gr. & 15.89 grain equally if not damaged.

Fit good in the breech and accuracy is good.

Every orders had skirts damages.

Superb accuracy from my PCP guns...this is the lightest pellet I care to shoot in .22 cal...accuracy is excellent or always with JSB and their AA marked products.


...price....pricey pellets....but they are the best shooting...

By Rob E.February 12, 2018

I'm convinced that these pellets were speciality designed for PCP rifles of medium power or higher as long as they are not made by Crosman. They shoot magnificently out of my Air Max .22 Varmint (SPA 900, Diana StormRider, etc..) my XS-705-2 HC Sentry Deluxe and my Umarex Gauntlet. All of these rifles push the 900+ fps with these pellets, and are accurate enough to take head shots on Junkos out to 50+ yards in light wind ( 3-7mph) conditions, using a bi-pod. These pellets HATE every Crosman PCP I own. From the Disco, to the M and Prod. They also despise the NP and NP2 rifles. All 7 of them. All the Crosman's do pretty well with their own inexpensive CPHP and CPUM branded ammo, but can't touch the outstanding accuracy that the JSB's provide to non-Crosman rifles. That being said, as always, Your Mileage May Vary...

Wickedly accurate out of any medium to high powered PCP that isn't made by Crosman.

I bought these to try in my .22 caliber Gamo Bone Collector Maxxim. The pellets were all in very good condition: uniform head and skirt size, no dents or bent skirts. They were not loose at all, and fit in my breech very well. Snug. Just a little pressure was required to seat. Even though the pellet were a good fit in the breech, and in excellent condition, they did not shoot well from this rifle. Below are the stats of a 10 shot string from my Gamo Bone Collector Maxxim (.22): Velocity Min - 667 fps Velocity Max - 679 fps Velocity Ave - 675 fps Standard Dev - 4.21 fps Extreme Spread - 12 fps Energy - 14.53 fpe Best Group (25 yds) - 1.6 inches As a comparison, Here is what I get from H&N Sniper Magnum (18.06 gr): Velocity Min - 634 fps Velocity Max - 642 fps Velocity Ave - 639 fps Standard Dev - 2.54 fps Extreme Spread - 8 fps Energy - 16.37 fpe Best Group (25 yds) - .71 inches

Excellent condition. Very uniform. They fit my breech very well. Just a great looking/feeling pellet.

Poor grouping in my air rifle. Generated low energy.

Consistently accurate 3 of the 5 almost same hole

By DanielUSAOctober 28, 2016

If your barrel and these pellets get along (usually they do) their consistency in shape and weight give you much more reliable results. My 1st choice when looking for a particular weight pellet. Always JSB 1st then H&N 2nd.


More than most but not all guns like them.

By dustinUSAOctober 20, 2016

too shorrt would be decent for rotary pistols but very very short

well made

I tested these with Benjamin Trail NP, Crosman 1322 and Crosman 1322 with 23-inch barrel (and 15-inch barrel). On the Benjamin Trail NP I measured 692 FPS with 0.25 CTC (Crosman Hollow Point gives me 748 FPS less than 0.125 CTC regularly). On the Crosman 1377 with 1322 barrel I measured 437 FPS with 0.25 CTC (Crosman Hollow Point gives me 425 FPS with greater accuracy). On the Crosman 1322 with 15-inch barrel I measured 495 FPS (accuracy was bad due to loose barrel band, Crosman Hollow Point was 487 FPS with same accuracy issues). On the Crosman 1322 with 23-inch barrel I measured 510 FPS with 0.375 CTC and 0.25 POI shift versus 509 FPS and 0.25 CTC using Crosman Hollow Point. In summary, I found that these pellets are less accurate than Crosman Hollow Point pellets in the three guns (one with barrel change). I noted a Point of Impact shift that is equivalent to Crosman Destroyer.

Consistent sizing and speed

Less accurate than all Crosman Pellets that I have tested with (Destroyer (but with equivalent POI shift), Pointed, Domed and Hollow Point) with Benjamin Trail NP rifle and Crosman 1322 pistol.
