The Aguila Colibri is a .22 caliber round that travels at a blazing 375fps. The rounds do even have powder, they're just primer driven. They obviously wouldn't cycle an auto loader, but they're fun out of my Single Six. They hardly make a sound when they go off. Just a light pop. They won't draw any attention when fired at the stray neighborhood dog in your trash cans.
