  1. How do I re-prime my cases

To re-prime:

  • First you need to de-prime using a de-priming die or sizing die.
  • Next clean the primer pockets, with various tools available, to remove the carbon buildup.
  • Clean your cases and trim/chamfer if necessary.
  • Now your cases are ready to insert the new primer. This is done by either a handheld, press mounted or bench mounted priming tool. After this step you are ready to measure and load powder.
  1. What should I consider when reloading and handling primers?

When reloading and handling primers, consider the following:

  • Always refer to a loading manual to see which primers to use.
  • Test different primer makes to find the one that offers you the most accuracy
  • Avoid touching the primers with your hands, as oils can affect reliability.
  • Use safety glasses to protect your eyes from possible explosion and injury during priming of cases.
