If your set up didn't already come with them:
- Primer flip tray
- Primer pick-up tubes
In addition you'll need the obvious stuff like:
- good sturdy work bench
- Loading manuals (I gravitate to the bullet manufacturer's ones)
- components as you mentioned
Additional stuff that will make life easier:
- Case gauge (s)
- Lee factory crimp die (if you want to crimp)
- Good quality calipers (Starrett is a good example)
- Small long handled brush to clean the shell plate on ocasion
- Dillon bullet tray add-on
- Dillon roller handle
- A fellow shooter that has experience with the Dillon or just reloading in general will be a wealth of knowledge.
Good luck and happy hand loading!!!
