NOE Makes a Die Set for preparing Large and Small Primer Cups for removing the impact dimple on the base of a spent primer; and to resize the spent primer cup before “Remanufacturing” the Primer. I have gotten away for using the term Reloading Primers because a search on the Internet results in what seems to be 20,000 ads on Primers; most of which are out of stock or often SCAM sites. For this and other Primer Posts I will attempt to use the term Primer Remanufacturing. When I purchased my NOE Primer Dies they came with no instructions; and I could not locate instructions on the Internet – So I experimented and came up with the process/es I describe in this thread.

The first step is to obviously collect spent primers from brass one has previously shot or from range brass pick ups. I highly recommend at the start that reloaders seeking to currently or in the future Remanufacture Primers – keep all spent primers collected in at a minimum four different containers. I use empty plastic Vitamin Supplement containers for this purpose. This will keep those thinner Pistol Cups separated from the Thicker Rifle Cups, and of course keeping Large Pistol primers separated from Large Rifle Primers is essential as the Large Rifle Cup is slightly “Taller” than the Large Pistol cup.
I also take an additional step and sort out the “Brass Colored” primer cups from the “Shiny Silver Colored” primer cups for each of the Primer types. As an example; Remington Primers are all Brass colored, and CCI are shiny silver colored. Not sure this will be critical in the long run; but trying to reduce variables up front.
The next step is the most challenging to ones patience; separating the anvil from the Primer Cup. I have tried using a vise, vise grips, plyers of a variety of types to hold the primer cup while removing the anvil, but have settled on using a set of Forceps to hold the cup. I wear a leather glove on the hand holding the forceps because I have pinched my finger or hand a couple of times. I also use the leather of the glove to help trap the Anvil when prying it from the primer cup. The anvils are prone to flying out rapidly and being lost if one is not careful. The Dental pick is used to get the point between one of the Three Anvil Legs, then to pry it loose. Some will fall out with a slight touch – others will be like breaking loose a 40 year old rusted tight bolt.
Once the Cups and anvils are separated; I use an Harbor Freight Ultrasonic cleaner with water and a couple drops of dawn dish detergent and Lemishine for cleaning. I always clean the cups (Single type of cup LR/LP/SR/ or SP in each cleaning) in one session and the anvils in another session. This way I can ensure both are cleaned and remain separated prior to remanufacturing. I drain the cleaning solution off and dry on a n old towel or paper towels. Any cups still having any residue in them are scraped clean with a dental pick.
Primer Cup processing is the next step. Over a few hundred primers I developed the following process. The “Repeated Steps” came to being because of slightly flattened primer cups, some thicker cups, a single press not fully removing dimples, or after dimple remover some primers having had side walls expanded outward. Any way, this is what works best for me:
1. Place Primer cup on top of the appropriate ram punch (The NOE set comes with a Ram punch and sizer for LR/LP and a Ram Punch and sizer for SR/SP cups).
2. Place the appropriate NOE Primer Wall sizer on top of the Primer cup sitting on the Ram Punch. I screw the NOE 7/8 threaded Bolt (Press Anvil) in only about 2 full turns; this allows the ram to almost fully cycle giving a greater pressure to Iron out the Dimple.
3. Cycle the Press arm, pushing the Primer Cup through the die and then causing the Ram Punch to force the Cup against the 7/8 threaded NOE Bolt which as a small milled indent in it’s face. I lower slightly and rotate the cup 90 degrees and do a second activation of the Ram to ensure the dimple is ironed out.
4. I lower the ram, remove the primer cup, and remove the NOE sizer die from the Ram Punch.
5. I then seat the “De-Dimpled” cup on the ram punch once again, place the NOE sizer on top of the cup/ram punch once again and press the Cup through. I do NOT press the cup into the 7/8 bolt again as this could expand the wall of the cup – the cup sizing process is completed. Store processed cups in separate container (Pill bottles are good) for inserting Primer Compound into cups at a later time/date.
6. Take another cup and repeat steps 1 to 5 again until all Cups are sized. Much quicker than it seems after one does a few and becomes accustomed to the process steps.
