Thread on reloading primers (at a different forum) was promptly shut down by moderator.
Glad to see they're making more progress on the high road
http://www.aardvarkreloading.com/resources/Homemade Primer Course 2019-06-28.pdf will get you to the homemade primer course as mentioned earlier.
Materials necessary for above primer course can be purchased partly at hardware stores, and through places like skylighter.com and other pyrotechnic supplies.
Doing so, however, may not be legal in your jurisdiction; you're responsible for your own actions and checking your local laws, as your mileage may vary.
Where one could receive a medal for good citizenship in some places for some actions, such in others (think: blue liberal states) can be a crime.
As noted, compounds in homemade primer course are corrosive, and after using, it's necessary to wash out firearm with hot water to ensure removing corrosive compounds.
Manufacturers state they're producing primers, and while possible to reload primers, I would much prefer purchasing non-corrosive primers when they become available.
"Wikiarms.com ammo search" for reloading can be setup to notify when primers are back in stock.
In the meanwhile, there is a workaround for the "ammo-less" getting enough daily practice improving one's proficiency:
