Sierra Sports Master Handgun Bullets .40/10mm .400" 150 gr JHP 100/ct
$46.74
Sierra Sports Master handgun bullets in .40/10mm caliber give reloaders a proven platform for building dependable defensive and practice ammunition. These 150-grain hollow point projectiles are sized at .400" diameter and come in a convenient 100-count box—enough to load several hundred rounds without breaking open a fresh container. Whether you're working up loads for a .40 S&W, 10mm Auto, or similar cartridge, the Sports Master line offers the kind of consistent performance that keeps you confident on the range or in the field.
What sets these bullets apart is the serrated power jacket design on the hollow cavity. That serration pattern creates controlled expansion when the bullet meets its target, allowing energy to transfer more efficiently while helping the projectile retain its weight through the expansion event. For handgun hunters and serious defensive loaders, that combination of penetration and expansion matters—it's the difference between a round that performs as intended and one that leaves you guessing about what happened downrange.
Sierra stands behind the materials and manufacturing quality of every bullet, a commitment reflected in their reputation among reloaders who trust their components for serious applications. If you're loading .40 or 10mm ammunition and want projectiles that expand reliably across a broad velocity window, the Sports Master hollow point deserves a spot in your reloading bench.
