The lightest variant of ammunition with half round head from this company. RS stands for Rapid Speed (ultra fast),because the velocity is much higher than with conventional ammunition. Also the ballistic curve will be very flat. There is also connection with the automotive industry, where RS (Rallye Sport) is the nickname for lightweight and high-performanceversion of the car.
Each barrel is specific and unique in its own way. Differences in hundredths of the diameter of the pellets (5.51; 5.52; 5.53) then serve precisely to make it possible to find the ammunition for the given weapon with which you can achieve the best results in the target. But all these diameters fit into all 5.5mm caliber air rifles without any problem.
The JSB company also offers a test set of airgun pellets, where you can already find ammunition of different diameters and weights, and choosing the ideal ammunition for your weapon 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
conditions, Air Arms S510 TDR R 5.5mm weapon, Garmion Xero C1 chronograph:
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
