It would help to know what bullet you are going to be loading or what you are going to be shooting and at what ranges. Do you have a velocity in mind? Do you shoot Barnes bullets or Speer? Do you have a prefered powder?
You really need to either get a few reloading manuals, (you can get free pamphlets from powder makers where you buy your powder) or locate and use the powder company's load data websites that are available to the public.
