Frontier 10mm/.40 200gr CMJ RNFP Bullets – .400″ (500)

The Frontier 10mm/.40 200gr CMJ Round-Nose Flat-Point bullet is a heavy handgun projectile designed for consistent accuracy and dependable ammunition reloading.

Its 200-grain weight and .400-inch diameter make it particularly suitable for compatible 10mm Auto loads. It may also be used in selected .40 S&W loads where appropriate published data is available. The RNFP profile combines a rounded feeding surface with a flat frontal area, making it suitable for target practice, training and practical shooting.

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

Important: These are component bullets for ammunition reloading and are not loaded cartridges. The 200-grain projectile occupies more case capacity than lighter bullets and can increase pressure if unsuitable data or an incorrect cartridge overall length is used. Always use published load data specifically covering a 200-grain bullet in the cartridge being loaded. Begin with the recommended starting load and confirm the correct overall length and crimp for the firearm.
