What This Cartridge Was Designed to Do
The 8mm Remington Magnum is a belted magnum sporting cartridge developed for long-action hunting rifles. It combines 8 mm projectile diameter with a large magnum case and is maintained today chiefly by handloaders and owners of discontinued factory rifles.
Typical Rifle Platforms
- Remington Model 700 rifles originally chambered for 8mm Remington Magnum
- Custom long-action hunting rifles with a verified chamber
- Other factory rifles specifically marked for the cartridge
Compatibility warning: Match the brass to the exact chamber, reamer specification, dies, and rifle. This is especially important for proprietary and non-standardized ELR cartridges.
Best Suited For
- Long-range hunting
- Large-game sporting rifles
- Collectors of discontinued Remington chamberings
- Handloaders seeking new correctly headstamped brass
