My only shortage during the current ammo crisis was percussion caps. I mentioned the problem to my metalsmith who shook out a few into a bag for me. When I said they looked old, he told me they went back 40 years. That reminded me I had some after all. For some reason I've held on to some I got as a kid but later felt were of no use. I dug out five tins of Fiocchi # 11's and found they work jusy fine after 65 years.
