Reference Reloading Guide:

This will give you a general knowlege of the steps you will take in reloading. Also, most general proceedures like this are under the assumption that you will be reloading once fired brass so you will start with the sizer (de-primer) die.
If you are reloading new factory brass you do not necessarily have to re-size it. It's an option.
One of the most critical aspects of reloading along with determining the OAL (cartridge overall length) will be the case length (trim). The case length trim will be listed in your reloading manual. This should be done wheather it is new brass or once fired brass. This is not a one time deal. You will do this proceedure everytime even if the brass has been reloaded before. Why, largely because of case expansion. The brass of the cartridge will never contract. In the remote possibility that it is contracting it is most likely expanding in another part of the case. When the case expands it will make the wall of the case thinner and thinner in time. It's always a good idea to resize your brass before you measure with calipers its case length. There's not much give on the subject of case length trim. It has to be pretty much on or between the designated demensions given in your reloading manual. The reason being, if a case is to long or to short it can lead to inaccurate bullet seating with some die's. And above all, if the case is to long or to short it can create what is called a 'cartridge head space' problem and won't be as accurate as it should be.

Let me give you another reloading reference guide that will assist in the reloading steps. Most of the web-site all have about the same information. It's just that some site's have a more coherent way of explaining these proceedures in a more user friendly way!
