Frontier 10mm/.40 180gr CMJ Flat-Point Bullets – .400″ (500)

The Frontier 10mm/.40 180gr CMJ Flat-Point bullet is designed for consistent accuracy and dependable handgun-ammunition reloading.

Its heavier 180-grain weight and .400-inch diameter make it suitable for compatible 10mm Auto and .40 S&W loads. The flat-point profile creates clearly defined target impacts and provides a consistent seating surface, making it suitable for target practice, practical shooting and competition use.

Frontier’s Complete Metal Jacket construction fully encloses the lead-antimony core in copper. The bullets are restrike-finished to improve dimensional uniformity and shot-to-shot consistency.

Important: These are component bullets for ammunition reloading and are not loaded cartridges. This flat-point version is a different product from the 180gr RNFP bullet. The 10mm Auto and .40 S&W require different cases, powder charges and pressure specifications. Always use published data for the exact cartridge and bullet weight, begin with the recommended starting load and confirm the correct cartridge overall length and crimp for the firearm being used.
