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.
You mean EDM wire cutting the rifling? You could technically angle the wire inside the barrel to achieve the proper pitch. But your pitch will be limited by the length of the barrel. Also is you angle a straight wire inside a tube and cut slots into it, the bottom surface of your slot will be parabolic. Not ideal for rifling since the pressure inside the barrel will steadily grow as the projectiles moves towards the middle of the barrel and then decrease past that. You got a video of somebody attempting that. I’d love to see that. Also EDM wire cutting at home is doable, but far from easy.
It’s more like rough etching away
