The ABCs of Reloading: The Definitive Guide for Novice to Expert
If you currently buy ammunition to shoot, start saving your brass (if you haven't already started). Sort it by headstamp. Brass can be a costly component to buy, it's nice if you already have some by the time you start reloading.
There are several reasons why folks reload...
1) It saves $ &/or allows you to shoot more for the same $.
2) It allows you to have a deeper understanding and connection with your hobby (shooting).
3) You can produce ammunition of higher quality than you can buy.
4) You can produce ammunition that is not available on the market today or is rare &/or expensive.
5) You can produce ammunition that you custom design for a specific purpose.
The reason I mention this stuff is that it will have an effect on decisions you will make about equipment you will be buying. Think about what you are trying to accomplish before you buy equipment.
Get the book, do some reading, ask questions as needed, have fun!
