My 7-shot double action MH in .32 loads backwards--at half-cock the cylinder easily rotates and clicks counter-clockwise for loading. It is possible, but requires hammer manipulation, to make it rotate clockwise while loading. Regardless of which direction you load, when you cock the hammer or pull the trigger through the double action, the cylinder rotates clockwise.
To end up with six cartridges in the cylinder and the hammer down on an empty chamber of your 7-shooter, when loading counter-clockwise you load three, skip one, then three more, cock the hammer (the cylinder will advance clockwise), and lower it on an empty chamber.
If you insist on loading in a clockwise direction you will probably need to pull the hammer back slightly each time you rotate the cylinder--you would then load two, skip one, load four more, cock the hammer, and let it down on an empty cylinder.
If you want to check for yourself and don't have dummy cartridges, number the cylinders with a Sharpie and try it out. The Sharpie should clean off with alcohol when you're done.
The large, six-shot single action Merwin Hulberts are similar, but they are definitely designed so the the cylinder turns clockwise when loading. With those you load two, skip one, then three more. The difference between the Colt's "load one, skip one" and the MH's "load two, skip one" is caused by the lower location of the loading port on a Merwin Hulbert.
