Johnl, you may also want to invest in a couple of good reloading manuals. I have 5 or 6 manuals that I use on a regular basis. I have found it helpful to buy the manuals published by companies that manufacture the bullet brands and/or powders you may be using. Lyman, Nosler, Sierra, Hornady and Lee all have decent manuals that I refer to often. Never hurts to compare details from one manual to another based on bullet type and weight. Also, Hodgdon's website is a great resource as well. Have fun reloading!
