Sierra 8340 Sports Master 38 Cal 158gr JSP Bullets 100/Box

The Sierra 8340 Sports Master delivers consistent expansion and reliable performance for .38 caliber applications. This 158-grain jacketed soft point bullet combines proven accuracy with controlled expansion for hunting and target shooting applications.

What Makes This Different

Sierra's Sports Master line features a unique jacket design that promotes uniform expansion while maintaining weight retention. The soft point construction initiates expansion at lower velocities compared to full metal jacket alternatives. Each bullet undergoes Sierra's quality control process to ensure consistent dimensions and weight uniformity within +/- 0.3 grains.

Key Features

• 158-grain jacketed soft point construction for reliable expansion
• Copper-plated jacket reduces barrel fouling and extends barrel life
• Precise .357/.358 inch diameter for .38 Special and .357 Magnum applications
• Boat tail base design improves ballistic coefficient and downrange performance
• Consistent weight tolerance maintains shot-to-shot accuracy
• 100-count bulk packaging reduces per-round cost for high-volume shooters
• Compatible with standard reloading dies and powder charges

These bullets perform effectively across velocity ranges from 800 to 1,400 feet per second, making them suitable for both .38 Special and .357 Magnum cartridges. The controlled expansion characteristics work well for medium game hunting within appropriate ranges, while the accuracy potential supports competitive shooting applications. The jacketed construction handles magnum velocities without separation or excessive deformation.
