If you have question which do not need own thread post it here. Ok I start.

If you know your gun shoot 90 m/s with .4 bb can you somehow calculate how much it shoots with .2 bb?

It's shooting 416fps on .2g bbs.

To use that to calculate the fps using different weights you first use the top one to figure out the energy (joules).

Once you find the joules you scroll down and input that in along with whatever bb weight you desire.
