“Where can I get some depleted uranium?”
At one time, it was used as ballast in aircraft. I don’t know if it is still used. Once the good stuff is removed, it isn’t that valuable.
Depleted uranium is extremely dense. Been used for decades as subcaliber penetrators in Sabot tank main gun ammo.
Used on the M-1 Abrams tank as ballistic skirting. Very difficult to breach.
DU has many uses. As anti-drone shotgun ammo it now has an additional one. How about a Remington Accelerator sabot round in 30-06, only with a DU core instead of JHP? Could easily reach 3 km aimed straight up at one of Holder’s spies in the skies.
