Sierra A937532 Outdoor Master .223 Rem 55gr HPBT Bullets - 20/Box

The Sierra A937532 Outdoor Master delivers consistent accuracy for competitive shooters and precision enthusiasts demanding match-grade performance. These hollow point boat tail bullets combine Sierra's proven manufacturing standards with advanced ballistic design for superior downrange performance.

What Makes This Different

Sierra's Outdoor Master line bridges the gap between standard hunting bullets and premium match projectiles. The hollow point boat tail configuration reduces drag coefficient while maintaining structural integrity through impact. Each bullet undergoes Sierra's multi-stage quality control process, ensuring weight consistency within 0.3 grains and dimensional uniformity that translates directly to tighter groups.

Key Features

• 55-grain hollow point boat tail design optimized for .223 Remington chambers
• Precision-drawn copper jacket with controlled wall thickness variation
• Boat tail base reduces drag and extends effective range
• Lead core swaged to exact specifications for weight consistency
• Compatible with standard .224" diameter rifle barrels
• Packaged in protective foam inserts to prevent damage during shipping
• Ballistic coefficient of approximately 0.243 for predictable trajectory

Field testing demonstrates reliable expansion at velocities between 2,200-3,400 fps, making these bullets suitable for varmint hunting and target applications. The boat tail design maintains stability through transonic transition, extending accurate range compared to flat-base alternatives. Temperature stability remains consistent across seasonal variations, with minimal point-of-impact shift between summer and winter conditions.
