Vacuum barrel pneumatic
A DB member asked me if it is worthy to have vacuum barrel (Tomba) on the pneumatic gun (Cyrano).
I asked him:
Is it worthy to have about 45% better performance: vacuum barrel (min 25%) + more hydrodinamic parts on the shaft (min 20%)?
This is true for the majority of pneumatic guns. For Airbalete performance could be better "only" 25% in shallow water. In deeper water more.
