A little different slant to the question.
As I gain years, I have determined that I need only what I will shoot up before I can reload them, again and again.
A thousands rounds of 'reloads' from an unknown source has little value when conspired to the components still in sealed/unopened packaging. I know my son, daughter, their spouses and close family have no problem shooting my loads (they do it all of the time) but how many of you would, with out a little concern?
I have 'sleeves' of unopened primers, boxes of shrink wrapped bullets and sealed bottle of powder stored away. I do rotate my stocks as I shoot up the older first.
Component shortage, yea, I see the complaints. Has little effect on my loading. Old people have old ways.
