When I first started reloading, primers were .39 cents, if you could find them. Surplus IMR 4831 powder was sold in paper roll top bags for .35 cents a pound. And I was making $1.25 an hour then, so it's all relative........
Sierra bullets weren't ever made in the Sierra Mountains. They were located on Painter Ave., in Santa Fe Springs, CA, which is right next to Whittier. I used to stop by there and buy factory seconds by the pound.
Hope this helps.
