Modern consistency for a cartridge with deep hunting heritage
The Gold Country Scorpion 139-grain 7mm (.284) bullet is designed for the 7×57 Mauser, one of the most respected hunting cartridges in history.
Many original 7×57 rifles operate at moderate velocities and benefit from bullets that prioritize reliable expansion, moderate length, and stable flight rather than modern ultra-low-drag designs. The Scorpion 139 was engineered to perform predictably within those constraints, honoring the cartridge’s legacy while delivering modern manufacturing consistency.
Why This Bullet Exists
7×57 Mauser shooters often need:
• Bullets that expand at lower impact velocities
• Traditional weights with proven sectional density
• Designs compatible with older barrels and twist rates
• A hunting bullet—not a match projectile
The Scorpion 139 delivers exactly that.
Primary Cartridge Application
• 7×57 Mauser
Also suitable for: • 7mm-08 Remington
• Select European-pressure hunting loads
