Botttom line here is you simply cannot write a simple single set of directions that is applicable to all makes & models of double guns, they have different features. Some guns can be dissembled & reassembled with the hammers either cocked or uncocked, others can't. Many guns can have their hammers lowered in the process of closing them, others can't. However after lowering the hammers by either method, "Most" guns will allow removal of the bbls after taking off the forend without cocking the hammers, maybe a few won't but they are I think in the minority.
