Whichever ammo is the most reliable in the gun. For the most part, the only way to know is to shoot different types of ammo through the gun.

Join a SERIOUS airsoft team(You must be skilled to do this), most will let you borrow a gun, and make sure they know that they are holding you back from getting into a sport.

Because if you are against gun safety, you're probably dangerous when handling a gun. Many people that are not for gun safety never will and don't know as much as they probably should know about their gun/guns they own.
For most guns, a value is derived from what a gun of that make, model and condition is selling for. If you know the make, model and condition, you can check references such as the Gun Traders Guide or the Blue Book of Gun Values. You can also check on-line auction sites, such as Gunbroker, and look at COMPLETED sales of a comparable gun.
