dragunovsks I suggest you start out by buying a copy of "The ABC's of Reloading" you can get it off of Barnes and Noble for $19.99
I suggest you get it fast because when I bought mine I picked it up for $15 off of Amazon , it seems reloading books are getting scarce and expensive .
Lee's "Modern Reloading Second Addition" is also good as well as Speer and most other makers manuals .
You will save money in a manner it all depends on how expensive/fancy you get with your reloading setup and how often you shoot .
For straightwalled case's such as 38/357 , 40 , 45 is pretty simple and you can use what are called Carbide Dies and no lube with the bottle neck cases for rifles you MUST lubricate the cases to run them through a resizing die .
You can get started reloading with the least amount of cash layout with Lee equipment I have used it for 20+ years and it gets the job done just fine , it might not get it done as fast as a Dillion but it costs hundreds less .
Describing everything you need to do and what you need would make for a hugely long post , you can search the web and find almost anything you need and perhaps print it out and create a book rather than buying one .
If you have yahoo messenger with speakers and a microphone I would be willing to voice chat with you and explain most of your questions .
