If you have not made any purchases get a good reloading manual or two or three. Cross reference between them all. Then get a single stage press by RCBS or Redding. If Redding, get the Big Boss, the RCBS get the new Rebel or Rockchucker. Either of thee presses will last a life time. You can purchase better or quicker or more convenient but in the end, these will do everything you want and can be the basis for all your reloading. A good powder scale and powder throw. I like the old fashioned beam scales but the new electronic scales work well. None are cheap. Neither is the scale weights which are pretty much mandatory to check your scale. (the scale weights are eye watering expensive considering what you get in the box, but again, they last forever and its what you need to make sure what you want is what you are getting.
In reloading, getting the loading right (as far as powder, and charge weight and bullet weight)is very important, a bad choice or a mistake can lead to pretty serious injuries.
