Cartridge Overview
The .500 Nitro Express 3-inch is a classic British large-bore cartridge developed for powerful double rifles and certain single-shot sporting rifles. It became associated with close-range dangerous-game hunting and remains an important chambering among collectors, professional hunters, and owners of bespoke British rifles.
Rifles and Platforms
- Historic British double rifles chambered and regulated for .500 Nitro Express 3 inch
- Modern bespoke double rifles built for the exact cartridge
- Single-shot rifles specifically chambered and proofed for .500 Nitro Express 3 inch
Compatibility warning: Historic British cartridge; verify the complete 3-inch chamber designation and rifle regulation. Similar names, shared caliber, or external resemblance do not establish interchangeability.
Legacy & Context
The .500 Nitro Express occupies the space between the widely used .470 Nitro Express and the larger .577 Nitro Express. Its reputation rests on heavy-projectile performance from substantial but still portable double rifles.
Did You Know?
The case-length designation matters. A rifle marked for the 3-inch cartridge should be matched to 3-inch brass rather than selected by caliber name alone.
