The standard for measuring the power of an airsoft gun, is to state its velocity when using a 0.20g bb. The reality is that this system is a measurement in Joules, however most players find it hard to familiarize themselves with a Joule system. Every airsoft field chronographs guns with a specific weight of bb to establish the muzzle energy of the gun. At Feel Good Farm, where I play, the standard measurement weight is 0.25s. The limit at the field is 400fps with 0.25g bbs. This translates to 1.8J of muzzle energy. Once a player has chonographed, they may use any weight bb they wish. As you use a heavier bb, your velocity will decrease proportionally. An airsoft gun that shoots at 1.8J with 0.25s will shoot at 1.8J with any and all bbs. The velocity will vary based on bb weight. [Note: Technically, a lighter bb from the same gun will actually carry slightly more energy, due to the way velocity effects energy, but for airsoft energy levels, it is safe to say that the relationship between bb weight/velocity is linear.]
