I looked at your list of what you have and there are lots of good suggestions posted above. I just sat and looked over my reloading room and the list below are items I will not do without. Remember, tools that back up your power driven accessories work when the grid is down. Hornady New Dimension Dies work just fine for hunting rounds and I have used them for 30 years shooting out to 6oo YDS and that is farther than I will attempt a shot on live game. The below items are in no particular order. PRIMERS are key, without them no reloading can be done. You can do all your brass prep while searching for them, and reread your manuals. Stay Positive and you will score some eventually if you search diligently
Make a list, in order of operation, for your reloading procedure and post it on the wall in front of your press, step by step. Label everything or you will forget ( Trimmed and cleaned brass etc)
Uniformity and a careful step by step procedure will ensure consistent Ammunition!!
1. Universal decapping die
2. Stuck case remover
3. One Shot case lube and Lube Pad
4. Lyman case prep center does it all for your brass
5. A hand driven case prep tool for occasional brass work
6. Good Calipers and a Micrometer
7. Battery scale for a back up and reference check
8. Great lighting!!!
9. Hand priming tool (I use a RCBS)
10. Set of shell Holders (I use Redding to go with my T7 Press
11. Case neck brushes and Mica
12. Several dedicated reloading Manuals especially for the bullets you prefer to shoot. Nosler Hornady Sierra Speer Lyman 50th year version
13. Locking die rings if your dies don't have them (RCBS are best)
14. Powder trickler
15. Case trimmer (I use RCBS) it can be run by hand or by drill/screwdriver etc)
16. Read and reread the reloading manuals.
17. Case cleaner (I use a RCBS Sonic, Works great and no noise) Lots of good options out there.
18. Wrenches, Allen wrenches Dedicated to your reloading room.
Much luck and good shooting, you came to the right place
