Like others have said, "Any ammo beats throwing rocks!"
On the serious side, one commonality in all the threads for the last 6 years I have been on forums, most everyone likes to shy away from the Winchester White Box ammo in .22 rim fire, unless they are shooting something besides a semi-auto, and the same thing for center-fire. I have no problem with .38 special or any of the center-fire rimmed cartridges.
My perception of the PMC is that it is a superior cartridge to the WWB for semi-autos and probably equal to Fiocchi or S & B and a step above Aguila.
I have a fair amount of PMC in my larder.
When ammo is plentiful, you have your preferred brands that you buy. Those are the ones that have proven to feed well and have a very high expectation of consistency in powder charge, reliability of detonating, and a reasonable degree of accuracy for the firearm it is fired in.
As we get into ammo situations like we are in now and have been in before (this is officially the worst, I'm the official who is declaring this as official), we do look to alternative brands and manufacturers just to have ammo. If you are an ammo snob, you either have a warehouse full of ammo, or you learn to buy what you can get at a reasonable price for the time period you are in.
This is my third Rodeo, so I haven't been all that concerned for myself and my needs, but if I see a "buy" on anything, and I have the money to invest, I will...even if it is Wolfe, Tula, Brown Bear or Hotshot.
I wish 10 days ago I had been able to buy 10 boxes of Federal Champion 525 count boxes for $24.95 each, they are up to $40 now and people are buying them if they can find them. I expect a 50 pack of long rifle to be going at $5. Gather good values on ammo when you are able to.
My ammo larder is tiered in self defense, target and SHTF ammo as to my preferences I.
If during lean times, I do go shoot, I will use up my bottom tier ammo if just plinking or target shooting as I don't want to deplete my better stuff. If a friend has no ammo and wants to go shoot some, I'll sell him some of my lower tiered ammo, and he will be happy to get it.
Premium defensive loads are still available at a price, if a friend wants some of those, he can go buy them, but if they ever became hard to find, I would only sell a friend enough to fill his revolver or 10 rounds max.
Assuming we do see an easing of this gun and ammo situation (we certainly hope so), then you can start selling off or trading your lower tier stuff and replacing with your preferred stuff.
Right now, I'm not predicting this situation will go away as the moon, stars and planets are all aligned for bad karma, and one more mass shooting will be a pretty long nail.
To an outsider looking in, it must look like the United States is getting ready for war with itself, and even to a few insiders like us. If all the frenzy buying stopped today, and we were back to times like a year ago, it would take a full year to get the shelves and warehouses restocked if it would happen that soon. We have added so many new shooters in the past 6 years and in the last two, that becomes a factor. I have a "buy" on for ammo in my investment portfolio. With the reasons listed, and also nearly certain ammo tax to come, investing in ammo is a no brainer.
