> if you can make a gun, you can certainly make ammunition

theoretically true but having re-sleeved ammunition, the chances of injury is tremendously different. That said, a lot of people in California are having to resort to re-sleeving ammunition, not out of choice but because for all practical purposes, California has made buying ammunition impossible.

While you can crawl and bite your way through getting a horribly castrated gun in California, the real struggle begins buying affordable ammunition.

For regular people to own a gun that you can actually use in California, (not LEOs or certain other people), you either needed to have inherited them or bought them from the cartels. Otherwise you own something of limited use that insanely expensive to operate.
