Used primarily for .22 and .30 caliber cartridges used by law enforcement officials and military tactical shooters these bullets boast a frangible copper tin core made from powdered-metal. Unlike similar bullets on the market these have a unique gliding metal jacket. With this bullets remain intact even when handled roughly as well as during feeding and firing. Because of the design rarely is there a problem with gun jamming caused by bullets that fragmented prematurely. For the .22 caliber the bullet is a hollow point flat base made without lead. Unlike reloading bullets made at home these provide serious performance.
