JSB pellets manufactured in the Czech Republic by Joseph Schulz are considered by many to be the most accurate pellets available in the entire world. The RS stands for Rapid Speed because the velocity is much higher than with the regular pellets. Also the ballistic curve will be very flat. There is also a connection with a car industry where RS is nickname to their sport models (Rally Sport) which are lighter and more powerful than the regular ones.

Shooting these at 780fps (about 18fpe) out of my avenge-x. Shoots hole in hole at 30 yards. Brought it out to 60 yards not really expecting much. It shot an inch group with most of the group being less then half inch of each other.

Does not like wind, but that is to be expected of such a light pellet. Had to hold over 1.5 mil at 60 yards in very light wind. Also, I would have liked an option for a smaller count tin. I would have been a bit upset if these did not work for my gun and had 500 worthless pellets.

Airgun Depot has the best care for packages . These pellets shoot great out of my Diana 34 , @ 25 yards I get 3/4" to 1" groups all day , they hit hard and fast I don't know how fast no crony. I am 56 years old a welder for 38 years my eyes are not the best but I have no problem hitting 1 1/2" dots @ 25 and 30 yards with open sights .

The best so far

You've no doubt heard the phrase "First impressions are important". I'm 71 and a newbie at online ordering. This is my second attempt. My first was with Wally World and a pick up at the store. Ordered several tins and 1 cardboard box of 1250 C. Premiers. They came shipped in to large of a box with very little padding so they flopped around badly during shipping. Tins were dented and the box of 1250 split open, pellets were everywhere in the packing box. Several were lost due to a hole in corner of shipping box. I refused the order and got a refund. I'm old school and like to see and feel what I purchase. After pouting awhile I thought I'd give it a second try and did some reviews on Air Gun Depot and gave them a shot. I wanted to step up to a better quality pellet and tried the JSB's. I was so impressed with the way I was treated from the start. Liked the website and the way they communicate with me also wanted someone I can "Talk to". These are "Air Gunners" that shipped them for sure and not just a guy in a warehouse someplace. How do I know, simple the way they were shipped! Wow, I was expecting maybe 2-3 weeks getting them and was surprised to get them in less than a week. Plus I can track and tell just when they arrive, , , cool. Then they come in a box specifically suited for the size and amount of ammo I purchased, (4 tins). Not flopping around in a large one. They were wrapped in dense foam precisely the size needed to fit both tin of pellets and the shipping box. Treated and wrapped like a newborn leaving the hospital. When I looked in the tins the pellets were as I expected in great shape. Not a bunch of bent skirts and even has a foam pad in the tin to take up space. JSB cares and so does A.G.D. If they care this much about shipping ammo I have confidence in ordering optics, or a gun. I guess you can tell I will be a steady customer for my other air gun needs. First impression, you betcha it means a lot. PS; The JSB's are shooting great out of my 1968 22 cal Winchester 427 Diana, and grouping well. Will try them in my other guns soon.

Finally a good experience!

Not a huge deal but the JSB tins are a little difficult to open, maybe I need more practice.

I have been using my my 30+ year old Mendoza Magnum with a new spring and seals and these lighter pellets work amazingly accurate for hunting rabbits, squirrels and other small game. I am also impressed with the groups obtained shooting targets at 25ft(0.60") and 50ft(1.25") with the JSB Diabolo Jumbo RS .22 @ 13.43gr. The price at Airgun Depot when you buy 3 and get one free makes them a pretty goood deal too.

Lighter and faster with almost same punch as comparable 14.3gr pellets. Very accurate.

Metal Can should have a screw type lid to make it more practical but not a big deal.

By Joe DUSADecember 26, 2017

Many of the skirts where damaged because they are so thin. Gauntlet really liked them but you had to pick the bad ones out before sighting in your rifle.

Very accurate

Many many many damaged skirts very thin Would not order them again.

By CaseyUSANovember 15, 2017

Just realized I ever them today and I bet I've thrown as many away as I have shot the skirt is so thin that it easily bends out of round but the ones that don't have any blemishes are amazing good penetration and expansion

Expansion and accuracy

Skirt is too delicate attached photo of one I just pulled out of can

Good clean pellets, consistent weight and size. But not a good match for my Ruger impact... very short pellet also.

By BrianUSAJune 16, 2017

Pellets are very consistent in size. I haven't weighed them. I'm not sure I ever will... they had an extreme spread of 3 in one ten shot string and 2 in the second. They shoot 695 out of my 34 and are accurate. I am not a great shot, but can shoot a quarter size group at 25 yds.

Double foam padding in oversized tin.

Lighter pellet susceptible to damage.

Good results from my Walther Challenger Ultra using these pellets.Good price when using the buy 4 get one free offer from Airgun Depot. Excellent packing.All pellets arrived in perfect condition.

Well packed.Quality pellets.


By JoannaUSAAugust 27, 2016

Another good JSB pellet. Seem to work well in several of my springers but not nearly as consistent as the cheap Benjamin round nose in my stock .22 marauder.

Clean, well formed, consistent

Too light for my stock marauder

Has anyone tried these in a weihrauch hw95

asked Paul

Does anyone know the B.C. for this particular pellet. I can't find it anywhere. (JSB Exact Jumbo RS 22 caliber) Thanks Bill

asked Bill Waring


Billy from USA

I have read that pellet BC's change at different velocities. I know the 18.13 of the same shape yield an average BC of .032 so I would imagine .030 because of the lighter weight. Hope that helps.

Clint from USA

According to from the author of chairgun it is .030
