JSB Diabolo Exact Jumbo Monster .22 Cal, 25.39 gr - 200 ct

Long range for air rifles means different things to different people but, this pellet can really buck the wind for those longer shots.

They shoot awesome pretty accurate in my qb cheif can nearly hit previous shot hole at 30-35 yd

These and the 33.95 GRN. are about all I use in the Sumatra .22 cal. rifle I have. I have had very good groups out to 150 yards and the impact energy is unmatched by any other pellet I have used. I keep the speed down to 1080 for my high and 900 for my low and have found that both of these pellets will give outstanding results over and over. Both are my go to choice for pest as long as there are no range issues as these are very powerful at these energy levels(not back yard friendly).

As usual JSB pellets are very well formed and the skirt gives a very good seal. Accuracy in my Umarex Gauntlet and Marauder pistol is outstanding.

These rounds are heavy and will bring a great impact for plinking or hunting

I have only used these for target practice. shoot great. shooting 50 yards hitting very hard and feeding through very well.

groupings were all over the place with the Hatsan 95 vortex. May be ok for some guns but this one..nope

name says it all ..hits like a monsta

Nicely made and a cool design, but not accurate in my Hatsan Galatian.

I have a new Gladius Long, and wanted some heavy pellets for distance and stopping power and ones that would not be overpowered at the 6 setting. Bought these and the ultra shock hollow points to try some heavy pellets. While I shot same hole groups with the Jumbo Heavy 18gr, the Jumbo Express 14.3gr and the ultra shock 25.4gr, the groups with these looked more like a shot gun pattern most of the time at 20 yards. Also, the often felt rough and sticky.

In a quest to understand what was going on, I my used digital calipers to check head diameters. The ultra-shocks and the other two were generally about 5.47mm, rarely measuring more than +/-.01mm from that and being within about -.02 of the max diameter as I rotated the pellet. The monsters varied pretty widely, but tended to be about 5.50-5.51mm, with a high of 5.53 and a low of 5.46 for the maximum diameter, and often had significant measurement variations at various rotation angles on the same pellet, with some measurements as small as 5.43 on a 5.51 pellet for example. I think this is probably the source of both the scattered grouping and the variable sticky loading.

They do pack a punch, but my gun does not shoot them worth a damn. Obviously other people have not had the same luck. I may find something I can size them with, or may sort the smaller ones out, but right now the 160 in the tin are destine to be a paper weight, or go to toxic waste disposal at the dump. Maybe I just got a bad batch, but I obviously will not buy these again.

I never get out of the back yard, so these do all I need in a modified CO2 2240 with Maximus barrel. The targets are 8 - 17 yards.
Pellets giving 14.5 fpe at the muzzle. The last squirrel had no arguments. The last 10 yard target test was one pellet smacking
the back of the one before it. I am a lousy shot offhand, so everything is from a rest, but still good groups and plenty of power.

great price on a very consistent performing projectile

This pellet goes straight and accurate in my Hatsan BT65 at 1050 fps. 15gr go supersonic and are too unstable.

Good accurate pellet. Airgun Depo took extra care in packing them. Great packing no way any damage could happen. All pellets good no deformitys.

If u have a magnum power PCP, U got to try these pellets, the knock down power / penetration is amazing!
Accuracy is very good, when loaded one @ a time is compatible to Heavy Premiers.
I shoot / hunt a .22. cal Career II 707, dispatched a 100 + pound garden pest @ 28 yrd. w/one head shot !
I'm very protective of my tomatoes. I'm sure they would be effective on Jumbo Monsters or Zombies.

Accuracy is very good

Probably not the best for accuracy but serious knock down power

I only have the three 22's for testing but have some solid results. The Urban's are set up with Bushnell Trophy red dots. I only used a Caldwell front bag for a rest. Winds were relatively calm. 30 yards, 1.021" CTC, 5 shot group. AV = 637 fps, ES = 10.2, SD = 3.7 and FPE = 22.88. With chrono at the 30 yard line, AV = 589 fps, ES = 14, SD = 6.3 and FPE = 19.56. 14.5% loss of FPE at 30 yards. Unable to test accuracy beyond 30 yds until I go to the range. I plan on buying another U22 and putting a scope on it. This should tighten the groups considerably. I'm impressed with the results so far.
The Hammerli was just out of curiosity. Very windy on the day I tested. 30 yards, 2.5" CTC, 5 shot group. AV = 480 fps, ES = 7.5, SD = 2.4 and FPE = 12.99. Not bad for such low velocity. Acceptable for closer range pest control. I feel the gusty weather played a large part in the group being so large. When you consider the low SD and the accuracy achieved with the U22's. They were no key-holes and the pellets looked like they were stabilized in flight. I'll have to test on a calm day. That being said, I still feel these are more appropriate for higher power pcp's. Try a tin and see how they perform in your rifle.
My backstop was a fresh pressure treated 2x10 angled behind the Chrony. Pellets were in 1/4" to the skirt. Probably 3/8" - 1/2" deep or so at the tip.

Good product. Good stopping power. Great weight.

These pellets really packed a punch but were not very accurate in my break barrels.

I have a modded 2240 with 19 inch LW barrel with a 8" silencer on the end..at 20 to 25 yards these hit hard, Hard, HARD..with not 1 flyer..Dove, squirrel..even a head shot on a turkey and its done..my 2240 is tossing these out at 830 fps!!!

Hard hitting pellet, must try

My 22 caliber rifle hits as hard as a 25 cal rifle, thanks for an addition to my ammo selection.

With my purchase of the AirForce Talon SS PCP air rifle, I purchased several cans of pellets and also BB ammos because of the Colt Peacemaker that came free with the air rifle purchase. I purchased the JSB Diabolo Exact Jumbo Monster and the JSB Diabolo Exact Jumbo Heavy because of the good reviews that I have read about it. I got 3 tin cans of 200 counts each, 2 tin cans of 500 counts each, and 1 tin can of 500 counts at 25.39G, 15.85G, and 18.13G respectively. Now I can shoot non-stop for many hours during weekends....Got some BBs and 12grams CO2 cartridges too for my Colt Peacemaker.

I shoot these thru a Hatsan AT44 Long thats been turned up a bit.. Im getting 872 FPS measured at the muzzle & the pellet is still doing over 800FPS @ 40yrds. The BC works out to a incredible 0.066..

Hard-Hitting, Accurate & Very Uniform/Consistent/Clean Out of the Tin!

SOFT LEAD MUSHROOMS WELL, PEELING AND EASILY DISINTEGRATING. THE BODY SHAPE IMITATES CERTAIN ROCKET DEIGNS-AND THUS IS ABLE TO TRAVEL FASTER AND STRIKE THE TARGET HARDER, THAN OTHER HEAVIER PELLETS THAT ARE NOT SHAPED THE SAME. PLEASING TO THE EYE.

This is my hunting pellet of choice. doves at 75 yrds no problem, seem to buck the wind better as well.
Bought a talon tunes tophat swapped out the factory one and now I get great performance with these pellets but you need a powerful pcp to sling these babys

It hits super hard and fits pretty well in my Benjamin NP Trail.

These are definitely cheaper than you would expect them to be for their weight and amount. They definitely hit hard but the accuracy leaves me not feeling happy. I can get a grouping around the size of a tin of pellets. So overall they aren't bad. I will usually bring these out when I have a computer part die or feel like crushing an old DVD drive.

I purchase these when I was experimenting with heavy pellets in my trail np. I found these pellets to have tremendous knockdown power but they wouldn't group well. . I had better grouping with the eun jin 28 grain.

I use these in my hatsan125th.

my gas gun's are not doing well with these but the geneis NP shoot them very well sub 1" @ 30 yrds

In my last review I said the accuracy was very poor for these pellets. I've changed my mind on that. My pellet gun was very new at the time, and all the other pellets were very accurate accept this one. But after shooting it some more it seems to have broken in and works a lot better with these pellets. I can hit a milk jug at 75 yards with them, not bad at all! My only concern is that the skirts don't go all the way into the breech, but it doesn't seem to cause any problems. I got these pellets in .22 caliber for a Benjamin Nitro Trail.

They look very well made, every one is exactly the same and not a single deformed pellet in the tin. I can't hit the broad side of a barn with them though. Maybe they are just too hefty for the Benjamin nitro trail. They might work well with a more powerful PCP.

Nice heavy pellet! Using Stoeger X10 could NOT get a consistent grouping. Pellets were literally all over the target.

They shoot well. In my guns they do not group up as well as the lighter JSB's. They have serious knock down power.

These pellets are very accurate at 40 yards out of my condor.
