2.76" Remington Magnum case?

[CoElkHunter]

Would anyone know what intended cartridge would be made by cutting down a .416 Remington Magnum case down to 2.76"? There's a seller on GB that bought these from an estate sale and I am really curious as to what cartridge they could have been cut down for? Maybe the guy that cut the cases was just an idiot?

Brass looks not just trimmed but blown out, I dont see any shoulder.
