JSB Beast Jumbo, .22 Reviews

Not much. Accuracy isnt great in my Impacts (either rifle) and velocity retention no better than MR Grand which is supremely accurate in both rifles.

Not sure but something just seems to be 'off' with the design. Or...maybe a slug liner would work better both my rifles have pellet liners.

Need power, LOTS of it to move these. My one Impact i had 165 on the 2nd Reg to get these moving 1020 fps which is 78.5 fpe. Best accuracy was at this speed which was just under 1 inch at 50 yards. Didnt bother trying 100 yards as the Grand is FAR more accurate in both my rifles. Also..to move these at real speed my Impacts just gobble up the air my shot count shrinks dramatically

These have been my go to pellets for my FX Maverick (and my other PCP rifles) in 22 caliber. And I always get them from Pyramyd because of the great deal that they provide on these pellets and also because of their special and exemplary packing that they do to ensure that the pellets are not damaged in transit.

Quality control on the JSB end needs to be greatly improved.

Despite the excellent packing that Pryamyd Air does, I'd say the majority, at least the majority of these pellets, had deformed skirts. Usually, the pellets are perfect or close to that. These pellets are exceptionally accurate in my Maverick and have an excellent ballistic coefficient of 0.046. Clearly this is a JSB quality control issue and not a Pyramyd issue and I have addressed the issue with JSB directly. This is the first time I've ever seen this (skirt deformities) in these pellets because they're usually just in very fine condition.

Quick delivery, product as described, great quality

Nothing, seriously, they sucked

Not sure, could be bad design, could be bad quality control

I have a US made rifle that pretty much stacks at 50 yards with the Monsters, with the Beasts, I can get 3 on top of each other and then the next 3 are all over the place, consistently inconsistent. I'm disappointed really, was expecting much better based on my experience with the Monsters, considering it's single shot loading, I'd like to have confidence in that single shot and I don't get that with these pellets. Pretty much get the same result with my other 2 guns.

Like any JSB pellet this one is well done and very consistent.

Nothing

This is a very heavy for caliber pellet that needs a high power airgun to make the pellet work well.

The weight hits lke a ton of bricks

none

Great Ammo!

Nice pellet almost .22LR weight. I fire these out of a .22 muzzleloading homemade rifle. Groups are very tight.

Nothing.

These are some best pellets I`ve ever shot! The groups are very tight. The pellets out of tin, you can see there very well made.

This was a reorder, Hope to be able to get more in future...

Make them more available...

Get them while you can..

I bought these pellets to use in my Sumatra 2500 which was super loud with ordinary pellets of 13 grain weight, even with a silencer. I think these are the heaviest .22 cal pellets available on Pyramidair. Anyway, along with the silencer, these 34 grain pellets took the bark right out of the Sumatra. I can actually here the air in the gun when fired. I am very happy.

The price, but ya have to pay to play right?

Nothing

I like the brand with the .177 Air Gun

Nothing, perhaps offer a larger tin of these.

I tried this in the Walther Reign UXT PCP Pellet Rifle. These pellets did not work well for this rifle. The pellets grouped consistently, however, in the higher PSI's they shot low, but the grouping was consistent. As the PSI's decreased the shots improved. To improve the shots, I had to readjust the scope and I found this burdensome. I do not recommend these particular pellets for the Walther Reign UXT. The best pellets I found for this rifle is the Baracuda 21.14 grams.

Make sure you have a .22 60+FPE gun to shoot these accurately. This is the last stop (in grains) before you have to purchase heavier, custom slugs. I only have two .22 guns that like them: A 70FPE Daystate Wolverine HP, and a 90FPE Sumatra 2500.

Larger tin count with screw top lid.

I've only loaded them single shot. Believe the Sumatra magazine will load them reliably.

Not bad for about 40 yards.

The butt end of them is a little to big.They could stand to drop a little weight.

Nope.

Well these things are really a beast of heavy lead that really will penetrate anything because of the mass.

I wish they throw at least another 50 in the box because they are a little bit expensive

If you got the power to push these things out they will definitely knock over whatever you hit. I was testing them on a 4 by 4 block of woodand it knocked it over and it went flying across the yard. Those little 15 grain pellets even 21's would barely move this piece of post material. I shot them with a crawl mega on full power.

As always with this brand, very good QC (quality control) all the ones I micrometered were exactly the same down to the hundredth. Weight also exactly the same on all of them I've weighed.

Not much of anything... Maybe more in a tin?

They originally shot horrible out of my condor with the 12" barrel at roughly 700fps with the .177 caliber valve tank. We're talking 3+ inch groups at 30 yards, with absolutely zero consistency. I then bumped fps up, and bumped the tank pressure down to 2500 instead of 28-2900psi, and started getting raggidy one hole groups (almost cloverleafed) at 30 yards. I then put the 24" barrel on and condor valved tank, and Im still getting them raggid one hole groups at 30 yards

Jumbo Beast is right. This is so big at 34 grain I can only shoot it as a single loud. I have a 10 round clip but the round is just a little tight to operate. It does shoot well and has a heavy impact at 50 ft. With a shot in the right place this round would bring down medium size game.

A little bit smaller diameter round to work in a rotary clip.

This is a hunting round. This ammo will destroy your metal targets.

These are great for any PCP rifle. I have shot these in my FX Royale 400, and it loves these pellets. They are heavy, great for small game hunting.

The skirt is a little long to fit in some magazines, but for my FX Royale no problem.

I do not like these pellets. . . . I love these pellets very very much.

Hits hard not the best in my air force rifle but still good

These are beasts for sure! Best suited for High pressure air rifles, although I did test them from a Nito Piston rifle. JSB Quality with Pyramid Air superior shipping. The photos speak for themselves. 14.3 grains vs 34 grains stopped by a steel target. Very uniform and high quality pellets!

Tough one. Fantastic in a PCP rifle. By nature they are long, so any grouping variances may come from slight deformation of the skirt when you close the breech on a break barrel.

Impact did not like them. I was able to get them up to 860fps Could not find a happy spot. Maybe I just couldn't get them fast enough.
