You should start with a reloading starter kit. Most starter kits have everything required except for the dies. The dies are sold separately. You would also have to purchase manuals for the type of bullets you would like to reload such as Hornady, Sierra, Barnes and so on. The reloading manuals have lots of information required for reloading. I have never used a chronograph and maybe in the future might purchase one but it’s not something on my priority list. I would rather put the money down on a RCBS powder digital scale. Good luck and be careful.
