GET A RELOADING MANUAL AND READ IT
A manual should be the first item purchased by a beginner.
The information in those pages will undoubtedly provide all you need to know. Actually, you should have 2-3 manuals-an independant source such as Lyman and at least one from a bullet manufacturer or one from a powder company. Preferably the last two should be from the powder/bullet makers you intend to use.
I do a LOT of reloading and keep 5-6 sources of information to check and cross check.
