RE: .243 win
Before you even think of reloading, buy yourself at least one of the major reloading manuals and read it from cover to cover. Reloading is enjoyable and saves you money but you really need a good source of data. I prefer the Hornady manual but they all have good reloading advise and date. A load that works great in one gun may not shoot worth beans in another gun. I have used the Hornady hollow points in my 243's and they are effective varmit getters.
