History
Introduced by Holland & Holland around 1907, the .500/465 NE uses the large .500 NE case necked to .465 caliber, giving it exceptional powder capacity and performance for a rimmed double rifle cartridge. It was a popular choice for professional hunters who wanted the authority of a .500 case but slightly reduced recoil for all-day use on safari.
