They slightly lower the fps of the gun but the bb weight increases inertia so they accually INCREASE the "punch" of the gun. Also, .25gm bbs are made much better quality than any other Bullets because they have to stand up to the internals of more powerful guns.2000 Rounds of 0.25gm ammunition from Excel, 6mm, industry standard.These BBs are perfect for gaming, although not 100% biodegradable Excel say their BBs are designed from an ecological view point.
