could you give some details of the availability or lack thereof of components during the last panic?
My apologies. I never directly answered your question and went off on my own tangent.
From my Northern California point of view, when the shortage first hit,
everything dried up quickly - powders, primers, bullets, & ammo. It became a matter of what rebounded and when.
The first to come back was bullets. First lead; then plated, then jacketed. Many jacketed bullets are still hard to find. I suspect that the bullets being produced are earmarked for loaded ammo first (think Speer Gold Dot bullets). I was at my LGS just a few hours ago and the Speer shelves are still mostly empty. Hornady (XTP) is better. Sierra is still unimpressive.
(I don't know what the heck is going on with Sierra. They don't seem too interested in their customer base - but that's for another post.)
Next, the primers started making a comeback. And none too soon - primers were my "choke point" with components at the time. A couple times, I had to use magnum primers for non-mag required loadings. (Which is no big deal - but that too is for another post.)
Powder seemed to be the most stubborn to make a comeback. It still hasn't come back here actually (the "new normal?" - that's right . . . for another post
). On line seems to show more stock than my LGS's (three in this area). But even at that, "good" powders (the ones I like) do show up with some frequency.
One thing I have noticed going back the last few months is primers . . . Primers seem to be going through a mini-shortage - especially standard small pistol primers.
All said, I don't think it matters much which components are harder to find than the others. You need them all to make ammunition; so get what you need of everything before the next shortage. <--- recurring theme there
