Sierra Sports Master 10mm Auto 165gr Jacketed Hollow Point Reloading Bullets - 100/Box

The Sierra Sports Master line of handgun hunting bullets is engineered to deliver reliable expansion and superb accuracy for serious reloaders. This bullet (Sierra part 8445) is designed for the 10mm Auto cartridge, measuring .400" in diameter and weighing 165 grains, making it a versatile choice for both personal protection loads and handgun hunting applications.

Constructed with a precision-drawn copper jacket over a lead core, the bullet uses a traditional Jacketed Hollow Point (JHP) design built for controlled expansion on impact. The profile is non-cannelured and carries a sectional density of .147, giving handloaders an excellent balance of penetration and downrange terminal performance.

Each box contains 100 bullets produced to Sierra's tight manufacturing tolerances for consistent weight, diameter, and concentricity. Whether you are assembling a defensive carry load or taking the 10mm Auto afield, the Sierra 8445 Sports Master offers the accuracy and expansion handgun hunters have trusted for decades.
