The 4 The Majority Of Functional Techniques for Recharging Primers

Shot-shell primers are used in cartridges with metallic components. 209 primers for pistols and riffles differ in their construction. The cups of pistol primers have smaller amounts of metal, and the mixture will burn more quickly.

The cap gun rolls cap method

This is the most straightforward method and it works pretty well for pistol cartridges that use fast burning powder. The primers produced using this method may not be sufficiently energetic for reliable ignition of slower burning rifle powders.

Marshall gives a list of the caps that are the best. He explains how to recharge the primer cups. He outlines the procedure for recharging the primers using the caps. Through the practice, two primers a minute can be produced. They are extremely corrosive.

Marshall's son in law recently tried 50 cartridges in 9mm. Three years ago, the cartridges were loaded with caps gun roll caps primers. They functioned just like normal cartridges that were reloaded. They were able to fire and feed without any issues.

The strike-anywhere, match-head method (detailed at TM-31-210)

It produces a bit more powerful primers, however it is slower to use. Each primer takes between 5 and 10 minutes to finish. These primers are corrosive.

Replicate the priming compound used by the U.S. Army before, during, and following WWI

The priming chemicals are extremely dynamic, extremely stable and have a very long shelf time. They can be highly corrosive. They are easy to make and only 3-6 parts are needed (there are minor modifications).

For safety reasons, the components are mixed dry in small amounts of less than 2 grams. The priming mixture is moistened after it is placed into the primer cup. After that, the anvil has to be installed. The process produces primers that can be compared to commercial primers with regard to reliability and shelf life. A careful and precise production of primers could be accomplished at a speed of less than one minute.

The U.S. Army compound chemicals consist of potassium chlorate (KClO3) and antimony sulfide (commonly stibnite, or Sb2S3).

You can make excellent primers by using just the three primary substances. Other materials are utilized to assist in long term stability and the ignition of slow powders. A dilute varnish/water/alcohol solution is commonly used to wet the mixture and as a binder. The process of combining ingredients and then assembling 209 primers does not require any chemistry.

Create your own chemical precursors

This process produces high-quality non-corrosive and non-abrasive primers. This process requires some basic knowledge of wet chemistry.

To create a non-corrosive primer compound, this method requires the creation of chemical precursors that cannot be purchased through regular commercial channels. The precursor chemicals carry a risks, and the wet chemistry synthesis methods need to be followed strictly.

Once the chemical precursors are created, recharging the primers replicates an earlier Ely method (whose patent expired). Once the dry mixture has been moistened, primeing chemicals are created within the priming cups. This is the best method to put the priming compound into the cup.

Dry mix isn't highly sensitive. It is made of chemical compounds that have been synthesized with some security. You can store it safely in small quantities. Recharging primers after dry mix is prepared is only several minutes each. Smaller batch-sized methods can aid in increasing production, however security requires that not more than a dozen or two primers are recharged per batch.

The recharging/reloading, or even manufacturing of 209 primers is well within the capability of the average hobbyist. It would have seemed impossible for me two years ago. Now I know better. It is information that deserves a wide public. Marshall Thompson, PhD and anonymous Internet publishers are to be commended for their work.
