New videos and reviews every day 6000+ reviews from our customers The lightest pellets with a semi-round head from JSB. Diabolo RS - Rapid Speed with the highest muzzle velocity designed for target shooting.
Every barrel is in its own way specific and unique. Differences in hundredths in pellet diameter (5.51; 5.52; 5.53) serve precisely to make it possible to find ammunition for a given gun with which you will achieve the best results on the target. However, all these diameters fit without any problem into all air rifles in .22 / 5.5 mm calibre.
JSB also offers a test set of pellets, where you will find ammunition of different diameters and weights and choosing the ideal ammunition for your gun will be much easier.

Unfortunately, I definitely cannot recommend the ammunition. Over the years,
I have tried several packs and always the same problem – a number of pellets
have a deformed skirt so that they won't even fit into the magazine. When
loading two magazines (2×10 shots, random selection of pellets from the box),
7 pellets were damaged (see photo), i.e. 25%. This is probably due to the fact
that with such a light projectile, the skirt material is very thin and easily
damaged even in the new packaging, which is transported by courier service from
the e-shop. Or it could be a manufacturing defect, hard to say. Therefore,
I use slightly heavier JSB Exact Jumbo Express pellets, with which I have not
experienced this problem. Even groupings at 25 m are less accurate with RS than
with Express.
Grouping tested outdoors, temperature 15 °C, pressure 1016 hPa, calm

JSB Exact Jumbo RS, 10 shots, average muzzle velocity 184 m/s (see photo)
JSB Exact Jumbo Express, 10 shots, average muzzle velocity 180 m/s
