The Weatherby BRASS303CT50 Select Plus delivers premium unprimed brass cases engineered for the powerful 30-378 Weatherby Magnum cartridge. These factory-fresh cases provide handloaders with the foundation for precision long-range ammunition that maximizes the potential of this high-velocity magnum cartridge.
What Makes This Different
Weatherby Select Plus brass undergoes rigorous quality control processes that exceed industry standards for dimensional consistency and wall thickness uniformity. Each case features precise flash hole placement and consistent case capacity that delivers shot-to-shot velocity variations within 15 fps when properly loaded. The premium brass alloy composition provides superior strength to handle the 30-378's maximum operating pressure of 65,000 PSI while maintaining case life through multiple reload cycles.
Key Features
- Premium brass construction rated for 8-12 reload cycles with proper sizing
- Consistent case capacity within ±0.2 grains across the entire lot
- Precise flash hole diameter of 0.080 inches for uniform ignition
- Uniform wall thickness tolerance of ±0.0015 inches
- Factory-fresh condition requiring no initial preparation beyond sizing
- Boxer primer pockets sized to 0.210 inches for standard large rifle primers
- 50-piece count provides sufficient quantity for load development and hunting preparation
The 30-378 Weatherby Magnum pushes 180-grain bullets to velocities exceeding 3,200 fps, making these cases essential for hunters pursuing dangerous game at extended ranges. Competition shooters appreciate the consistent performance in 1000-yard matches where velocity uniformity directly impacts vertical dispersion. The robust case construction handles maximum loads without primer pocket expansion or case head separation through normal pressure ranges.
