Yes...buy yourself a manual for the bullet you intend to shoot and use their load data. You have no idea of what went into "free load data" on the Internet and you really do not want to risk your firearm or body parts.

I am still new to reloading and I would echo what others have said about the single stage. There is a lot to learn at first and a progressive press will only make things more complicated. Start with the single stage. After a while you will have a better idea of what your reloading needs will be and how much time you can devote to this.

Reloading is a fun way to add a new element to your shooting.
