Casey- your FIRST step- go buy a copy of The ABCs of Reloading. Big paperback- you can find a copy on Alibris.com or Amazon.com.
READ that first.
Basic reloading equipment consists of a press, dies, a shell holder, scale for powder- and a supply of brass, powder, primers and bullets.
The simplest press is a single stage, and then you can branch out- turret press, progressive press, etc. But a basic single stage press can laod very good ammo- just not as quickly.
You can shop for USED equipment- difficult to wear out. But FIRST- read the book.
