Sierra Sports Master Handgun Bullets .40/10mm .400" 150 gr JHP 100/ct$46.74
Availability: In Stock
Sierra Sports Master handgun bullets in .40/10mm .400" diameter, 180 grain hollow point are built for handloaders who demand reliable expansion and consistent performance across a range of velocities. Whether you're developing ammunition for sport shooting, personal defense, or duty applications, these 100-count boxes deliver the precision and repeatability that serious reloaders expect from Sierra's engineering.
The hollow point design is engineered with a serrated power jacket—that distinctive ribbed cavity you'll see on each bullet. During impact, those serrations control expansion along predictable lines, promoting uniform mushrooming and maximizing energy transfer on target. Equally important, the design helps maintain consistent weight retention, so you get the ballistic performance you planned for, shot after shot.
Sierra has been producing handgun projectiles for decades, and it shows in the attention to detail here. Material quality and manufacturing consistency are backed by Sierra's commitment to workmanship standards. For reloaders who value repeatability and want bullets that perform the same way downrange regardless of velocity fluctuation, these .40/10mm projectiles are a straightforward, proven choice.
| Caliber/Diameter | .40/10mm (.400") |
| Grain Weight | 180 gr |
| Bullet Type | Hollow Point (JHP) |
| Count per Box | 100 |
The serrations on Sierra Sports Master bullets create controlled expansion lines. During impact, the bullet expands uniformly along those ribs, promoting consistent mushrooming and more predictable energy transfer compared to unserrated designs.
Yes. These .400" diameter, 180 grain projectiles are sized for both .40 S&W and 10mm auto handgun cartridges. Always verify bullet diameter and weight match your specific cartridge and load data before assembling ammunition.
Each box contains 100 bullets, so one box will produce 100 loaded rounds when paired with cases, primers, and powder according to your reloading manual.
Sierra designed these bullets to deliver reliable expansion over a wide range of velocities, so you can expect consistent performance whether you're loading lighter target loads or hotter defense-level pressures—always within safe load data limits.
