Thanks for your replay.
I ask in detail because we use pellets that our Federation provides, they are JSB Exact 4.5 (.177) / 5.0 (.20) and JSB 5.5 (.22)
With those pellets the maximum speed is:
244 (m/s) for 4.5
191 (m/s) for 5.0
178 (m/s) for 5.5
Springer and PCP 24 Joules Class:
296 (m/s) for 4.5
233 (m/s) for 5.0
216 (m/s) for 5.5
Because the organization provides de pellets with a standard weight for that caliber this gives more power if you use a heavy pellet and less if you use an express, and the same applies if you use a diferent subcaliber.
In my case in Spain I got 14J using my pellets and in Portugal 16J.
