Ammo specifically for 3D printed guns
As 3-D printed guns have evolved over the past 18 months from a science-fictional experiment into a subculture, they’ve faced a fundamental limitation: Cheap plastic isn’t the best material to contain an explosive blast. Now an amateur gunsmith has instead found a way to transfer that stress to a component that’s actually made of metal—the ammunition.

Que ATF classifying each round as a gun, in 3,2,1….

Seems to me the two big hurdles to making guns are rifled barrels, and making ammunition. The rest all seems trivial.
With ammo, the big hurdle seems to be making the cases & the primer. I wonder if anyone has ever tried a piezoelectric primer, instead of a chemical one?

Of course, you could go the other way: Use lower-powered black powder substitutes (which can be purchased in pellet form) and big, large diameter bullets. That would reduce the stress on the barrel enough to make it viable, and it reduces the amount of metal used. In fact, nothing says the projectile itself has to be made of metal.

Slap an EMT/GMAW nozzle on a CNC “platform”.
What’s the problem here?

I heard you like barrels, so I put a barrel on your cartridge so you can shoot while you shoot.
