I have two questions to ask regarding airsoft guns.

1. My friend dry fired my gas pellet gun around 10 times, it didn't have gas cartridge or ammo in it, is it possible that the gun was damaged?

2. The Kraken shoots 0.20 gram BBs at 370fps, what fps would it shoot if instead of 0.20 gram, 0.25 gram BBs were used?

Thanks for the help,
