whitroth (9367) writes "Lewis Page, of The Register, writes, "When the nail hits the cap in the cartridge base in a Liberator, the expanding gas likewise pushes the lead bullet off the end of the cartridge and down the "barrel" pipe. Much of the gas leaks past due to the loose fit and soft material of the "barrel". The lump of plastic with the nail (probably) stops the cartridge case spitting out of the back, which is pretty easy as the bullet pops out of the extremely short, basically smooth* "barrel" almost immediately with very little push from the gas required. Most of the cartridge's hot gas spills out of the muzzle without getting a chance to do any work on the bullet, which is the main reason the cruddy "barrel" doesn't (always) come to bits on the first shot and the cartridge case (probably) doesn't just spit backward into the user's face.

The Liberator's bullet emerges going very slowly and wobbling or tumbling due to lack of spin. It might go almost anywhere, though not very far, and is unlikely to do much damage to anything it manages to hit."

Back to making zip guns with *real* steel pipes, kiddies, until you have a 3D printer that can print with steel, or something that strong.
