Hornady 8740 Unprimed Brass Cases .357 Magnum - 100 Count

The Hornady 8740 unprimed brass cases deliver consistent performance for .357 Magnum handloaders seeking reliable, precision-manufactured components. These cases feature Hornady's uniform wall thickness and precise dimensions for optimal powder capacity and bullet seating consistency.

What Makes This Different

Hornady brass cases undergo multiple quality control inspections during manufacturing, resulting in more uniform case weight and internal volume compared to budget alternatives. The proprietary annealing process creates consistent neck tension across the entire lot, while precise flash hole sizing ensures uniform ignition. Each case measures within +/- 0.001" of specified dimensions, significantly tighter than industry standard tolerances.

Key Features

• Uniform wall thickness for consistent powder capacity and pressure curves
• Precision-drilled flash holes sized to 0.080" diameter for reliable ignition
• Multiple reloading cycles - typically 8-12 loadings with proper care
• Compatible with all standard .357 Magnum dies and reloading equipment
• Annealed case necks provide optimal bullet grip and release
• Case length held to 1.290" +/- 0.005" specifications
• Packaged in protective plastic containers to prevent damage

These brass cases perform consistently across temperature extremes and maintain structural integrity through multiple firing and resizing cycles. Competition shooters rely on the uniform internal dimensions for load development, while hunters appreciate the reliability in field conditions. The cases resize smoothly in standard dies and accept both jacketed and cast bullets without excessive neck tension variations.
