Reload used Primers
Reload Used Boxer Primers
A Boxer primer is composed to two parts--a primer cup and an anvil.
1. Remove the anvil from the primer with a small nail or other sharp tool. 2. Using a hammer and a blunt peening chisel or nail (with the tip ground flat) just smaller in diameter than the cup, flatten the firing pin indentation. 3. It is not necessary, but if you have the time vibrate/clean the anvils and cups. 4. Using one of two methods, recharge the cup. Method 1--pack the cup with finely ground heads (the white tips) of self-striking matches. Method 2--using an eye-dropper, place a drop of mercury fulminate in each cup and allow to dry.
5. Allow to dry if necessary. 6. Replace the anvil and gingerly place the reloaded primer into the priming device and insert immediately into a clean, deprimed case.
Mercury(II) fulminate is prepared by dissolving mercury in nitric acid and adding ethanol to the solution.
Disclaimer: Although it is easy to make, fulminate of mercury is one of the most unstable substances known. Almost every major ammunition manufacturer ceased using it years ago under edict of toxic substance legislation because of its mercury content and it may even be illegal to have in your possession. It is listed here for educational and historic purposes only. It should be considered an expedient cap explosive used only in a survival situation.
