Sierra Sports Master 8125 9mm .355 125 Grain Jacketed Hollow Point Reloading Bullets, 100 Count

Sierra Sports Master 8125 reloading bullets are designed for 9mm applications where dependable component quality and consistent construction matter. Each bullet features a .355-inch diameter, 125-grain weight, and jacketed hollow point design suitable for hunting-oriented loads. The streamlined profile supports reliable feeding and consistent alignment when paired with compatible cases, primers, and propellants selected according to established load data.
The Sports Master jacketed hollow point uses a copper jacket surrounding a lead core to provide a balanced combination of structural integrity and controlled expansion potential. The hollow point cavity is formed at the bullet tip, while the copper jacket helps maintain uniform construction from bullet to bullet. With a sectional density of .142, this Sierra component is engineered for use in appropriately matched 9mm cartridges and firearms.
Each box contains 100 bullets for handloaders who value repeatable components for load development, practice, or hunting applications. These bullets do not include a cannelure, making them best suited to cartridge designs and loading methods that do not require a roll crimp applied to a cannelure. Always verify bullet, firearm, and load-data compatibility before loading, and follow published reloading data and safe handloading practices. Sierra part number 8125 provides a convenient reference when selecting matching components and maintaining an organized reloading setup.
