Yesterday I found this cartridge . As I was buying some new Hornaday factory cartridges I saw a yellow stick-it on a cartridge box off to one side saying "22 carbine $ 4 each " .
I said “I’ll take one of those please” and continued on to the other tables. When I got home later I found the photo of that box and that I’d found another treasure.
The motto of this story is to not be in such a hurry…
