Welcome from Montana, and Mexico North (aka Calif)
Do a lot of reading, before getting much in the way of equipment. There is so many ways to go in equipment it's isn't funny. Keep us posted on what you are thinking, and what you wanting to achieve with your reloading in rifles and pistols. Maybe we can cut down the expense of getting the reloading equipment by not having to purchase items twice or three time. before getting what you really want to do the job. What distances are you planning to shoot at under 500yds or out two a 1000yds. Equipment needs are different somewhat. Your ES & ED really come into play at the longer ranges. You are probable thinking what's that. So look it up on the net for what's it's about. One piece of equipment that needed to start with is a chronograph, before getting anything else. Even for factory ammo. It's the old story, Wish I knew then, what I know now.
