Mushrooming - The controlled expansion of a bullet upon impact with a target. 2. Shaving - (shearing) The cutting of metal from the surface of a bullet due to cylinder misalignment in a revolver. 3.Skidmarks - (slippage) Form on the bearing surface of bullets as they enter the rifling of the barrel before the bullet engages the rifling.Skid marks are typically produced by revolvers and have the appearance of widening the land impressions at the nose of the bullet. 4. Blowby - The escaping of gases past a fired bullet while the bullet is still in the barrel. 5. Leading - (metal fouling) The accumulation of lead or bullet jacket material in the bore of a firearm due to the passage of bullets. 6. Patch - A piece of cloth used with a rod to clean the bore of a firearm. 7. Single-Action - An action requiring the manual cocking of the hammer before sufficient pressure on the trigger releases the firing mechanism. 8. Dummy ammunition - An inert cartridge which cannot be fired. 9. Muzzle wave - The air that is compressed and moves out spherically from a firearm’s muzzle after firing a projectile. 10.Muzzle Brake - A device at or in the muzzle end of a barrel that uses the emerging gas behind the projectile to reduce recoil.
