Properly cured powder coated bullets causing cartridge failure, long term ammo storage problems, eroding gun barrels, global warming, etc. is a horse that is dead and buried as far as I am concerned.
I went to the range last Tuesday and fired 200 PC rounds loaded 3 years ago and every single round fired as expected. So I would tell you not to worry about it. Load and store PC just like you would any jacket or plated bullet, but that is just Me. If you are still worried, then forget the PC completely and store copper jacketed bullets like the military does.
As far as a proper PC cure I would suggest you follow the actual Powder Manufactures Recommended Curing Schedule for the polymer being used. A proper cure is the only way to achieve all the benefits of PC. As this original post implies, many are not curing the polymer properly and instead of listening to the powder manufactures they are getting their information off You Tube, this site, some internet post or other dubious source. But once again that is just Me.
