One thing I forgot to mention about the straight walled cases...Most people like a roll crimp on their cases. In some cases a crimp is mandatory, like in a repeating gun (revolver or lever gun). It is important to trim all of the cases to the same length before reloading. Trimmers can be expensive, but the Lee trimmer is about the cheapest and it works just fine for simple trimming. This is so that when you crimp the bullets in, the crimps will be uniform from case to case. Setting the dies for a crimp is a trial and error thing. There are several good sources on how to do a crimp including instructions from the dies sets them selves. One more thing, since you said that you had a lot of 357 cases, sort your cases into like cases. I mean that do not mix manufacturers in the same lot. Do not mix Remington, Winchester, Federal, etc together. If all of the case you have are Speer then you do not have to sort of course. Unless they are all of the same lot, they still should be trimmed. There are several reasons not to mix, too long for this post. There are loads (pun intended) of things to learn. Read, read, read any thing you can get your hands on. As mentioned above GB has a lot of good reading in his post. Many reloading manuals have good instructions in them.
