Kind of off the thread's topic, but maybe interesting. .
During WW2, as PJ said, you could get some 22 LR ammo, but not much else. Many people did cast bullets. The dedicated varmint hunters with their 220 Swifts, or 22-250 wildcats (then) were kind of out of luck.
A machinist on the West Coast who was a fanatic shooter and varmint hunter started selling swages to make your own jacketed bullets, using the empty 22 LR cases as jackets. He sold them under the name Rock Chuck Bullet Swage, as he hunted rock chucks.
The guy's name was Fred Huntington, and the name of his company was later shortened to the initials RCBS.
You mighta heard of them.
