OR, instead of starting this thread, the OP could have done a few searches and found enough reading to last him for several years. he could have found discussions on beginning loading, improving accuracy, loading for bench rest accuracy, and so on.
there are numerous threads on this and other forums that could have given him everything he is asking and then some.
i get tired of people asking questions that have answers right there in the beginning pages of any loading manual. beginning reloaders do have manuals, right?
