JSB

JSB Match Diabolo airgun ammo got its start in 1991 when former owner Josef Schulz began producing ammunition for air weapons under the name JSB Match Diabolo Bohumin in Bohumin, Czech Republic. This is a brand of ammo you can trust and buy here at Pyramyd AIR.

A former active gun marksman and coach, Schulz had a keen interest and a personal perspective in developing precision airgun ammunition. Following his shooting/coaching career, Schulz began researching and developing high-precision, production airgun ammunition and the stamping machines used to do so. In 2008, JSB Match Diabolo a.s. bought Schulz's company and incorporated.

Today, the company produces the same high-quality, precision airgun ammo. Each batch is thoroughly tested in-house at the JSB facility in the Czech Republic. From procuring the raw materials involved in pellet production to testing the final product, JSB exercises complete quality control over every pellet it produces. It's this kind of uncompromising attitude about quality control and the hands-on way by which it's maintained that helps keep JSB at the top of the airgun ammo game.

JSB pellets are made to accommodate your shooting style in different weights, calibers, and shapes. Pyramyd AIR carries more than 30 varieties of JSB ammo in calibers ranging from .177 to .357 and in weights from 8 grains to over 90 grains. Head sizes range from 4.52mm to 9.04mm and all sizes in between. The slugs and pellets come in domed/round, hollow point, wadcutter, and cylindrical. Here are just a few of their ammo types.

If you're looking for the highest quality ammo at a good price, the JSB Match Diabolo pellets are some of JSB's most popular and come in two varieties, the Hades and the Exact. Like all JSB ammo, they produce accurate, consistent shots from the first trigger pull to the last using almost any model of airgun.

The JSB Beast Jumbo is another good choice if you're looking for heavyweight ammo for a high-powered air gun. This is the heaviest domed pellet weighing in at just under 34 grains. The sheer energy of the Best is what you need in a hunting pellet.

If you're a competitive 10m shooter, you should try the JSB Match Diabolo Blue Heavyweight. The consistency is almost perfect, because JSB examines each of these heavyweight wadcutter by hand using a magnifying glass to ensure consistent quality, pellet after pellet. They are exactly 8.26 grains with a head size of 4.50 mm. This is the ammo you need to compete at the highest level.

JSB pellets have always enjoyed a global reputation for quality and accuracy. In fact, it has been shown that most air guns are more accurate when firing JSB pellets. See what you've been missing out on. Check out the entire line at Pyramyd Air!

JSB KnockOut Slugs MKII .25 Cal, 33.49gr, Hollowpoint, 150ct

These have been the best shooting slugs for my FX Impact M4 700mm.Ive tried many slug weights and brands and so far these have been the best. Same hole at 50 yards and MOA out to 100 plus yards. Using factory settings 100 bar reg,16 on macro and 4 on micro they're shooting about 870, and keeps the same zero as my AEA 33grain pellets so that's nice.

JSB Exact Jumbo Monster Light .22 Cal, 20.83 Grains, Domed, 200ct

These are fantastic! My 22 cal AvengeX was shooting 18 grain pellets just a little too fast (about 930fps., and 25 grain pellets way too slow. I put these 20 grain pellets in a mag and the AvengeX was shooting in the goldilocks zone (890fps.) I could've easily tuned the rifle to shoot the 18 grain pellets at 890fps just with a small hammer spring tweak, but I kinda like the added power I get with these slightly heavier pellets. Plus, I have too many .22 cal PCPs that shoot 18 grain pellets anyway. I can see these becoming very popular.

JSB Redesigned Exact Jumbo Monster Shallow Skirt .22 Cal, 25.39 Grains, Domed, 350ct

These shot the absolute best in my BRK 22cal Ghost HP. I tried several different 22cal. pellets, and these were by far the most accurate. I shoot these at 921fps, and they work wonders on the hundreds of Starlings and Crows I have shot with them so far. I will definitely be ordering more of these, especially with the Pyramid AIR buy three and get the fourth tin free.
