Meet the .960 caliber JDJ Fat Mac, a firearm I only just learned exists.

One pound at 2,200 FPS is a mere 38,685 foot pounds muzzle energy.

Lunatic: But it has a muzzle brake.

Cartridge: I sneer at your muzzle brake. Prepare to suffer serious injury or death!

If you want one (and find someone willing to part with one of the only three manufactured), you’ll only need around $100,000.

And oddly enough, despite the well-over-half-inch bore, you don’t need an NFA tax stamp. It has a “sporting use” exemption. Darned if I know what you’d hunt with it… on this planet.

I admit it: I want one. Because. If I win the lottery, I may not tell anyone, but there’ll be signs.
