When I was young, my dad owned a bolt action 30-06 rifle and a lever action 30-30 rifle, which he used only for hunting, as we were poor and needed the food, and ammunition was expensive.
Both rifles required manually operating the bolt or the lever to eject a spent cartridge and load the next bullet, then pull the trigger. They held just a few bullets in their internal magazines. I suppose they were semi-manual.
And guess what? The government didn’t try to take his guns, the Russians never invaded, and he never had to shoot anybody.
