The legislation concerning airguns has been changed. It was discovered that nearly all air guns would break the 500 FPS rule that separates airguns from rifles and shotguns if Prometheus pellets were used. The government is now using a policy that looks at both the velocity and ENERGY of the projectile. With the new standards it seems that only air guns that are designed to shoot 177 or 22 caliber lead pellets at velocities of over 500 FPS will be classed as firearms. Basically speaking they have juggled the laws to make Prometheus pellets a non issue. AIR GUNNERS CAN BREATH AGAIN! You have a reprieve from hell.
