Interesting but seems like an awful lot of work. I have no shortage of primers, I buy in bulk to help cut the cost of the hazmat fee and store them in nice dry places (in several different areas of the shop in containers that are sealed but have blow out plugs in case of a mass detonation). I have primers that are over 20 years old and have never had any problems with them at all.
