A catastrophic accident on board HMS Thunderer in January 1879, in which a 35-ton 12 inch muzzle loader hung fire and was subsequently double-loaded (causing catastrophic failure when fired again), motivated the Admiralty to re-consider the rifled breech loaders, as it is generally impossible to double load a breechloader.
