So yeah you can fire a bullet so many different ways, a rusty nail and hammer will do the trick. Isn’t the real problem the frickin bullet?
I swear in Sweden or something, you can take a gun home but ammo is only sold and consumed at the range and not for taking home.
Sure, you can make this a hollistic approach regulating guns and ammo, but the ammo seems to be the bigger issue here. You can make guns easy peasy, but ammo is much harder to manufacture and easier to regulate.
Too small, too prone to “spoilage”, and waaaayyyy harder to calculate existing stockpiles. It just wouldn’t be practical.
Mind you, that’s ignoring any of the should factor, and I am absolutely unwilling to engage in that debate
Edit: also, it’s too easy to improvise ammunition for simple firearms. You can’t really shove just anything into an autoloader and expect it to feed, but anyone with a machine shop could crank out something that would work, and the supplies just aren’t trackable the way something like ammonium nitrate is
