Review:
JSB Exact RS 4,52mm

The lightest pellets with half round head from the JSB company. RS stands for Rapid Speed because the velocity is much higher than with conventional ammunition.

After trying many options, this finally looks like ammo that works well with the Gamo IGT rifle. If I manage to get better results over time, I’ll add another photo.

  • It seems that with this ammunition you can get a decent grouping with my Gamo!

  • the RS Rally Sport are very good for CO2 pistols, since these have roughly 3 joules of power. pretty good grouping at 8–10 m.

  • Precise hits
  • Pure satisfaction
  • You can slightly smell the barrel, like when steel is being burned.
  • But that’s probably because I haven’t really broken in my GAMO air rifle yet.

  • Ideal for pistols and weaker air rifles such as some Slavias, Umarex air rifles for juniors, and the like.
  • Given the intended use and parameters, it is not suitable for longer distances.
