Some brass is much easier to use with moon clips. I use Winchester for the most part, but I reload just about everything I shoot. If a piece of brass is difficult to load or unload in a moon clip it gets tossed with the brass to be used in autoloaders.

To unload the brass I use 2 sharpie markers (or anything else with a similar diameter). One marker goes through the moonclip to make it easier to hold onto, while the other is inserted into the brass used to extract the brass piece. To load I just use my fingers.
