SNS Cast Bullets .40 Cal/10mm (.401") 180-grain flat-point lead bullets are engineered by competitive shooters for reloaders who demand accuracy without breaking the bank. Each box of 500 delivers consistent, polymer-coated cast bullets built from a proprietary 92% lead/6% antimony/2% tin alloy. The 18 Brinnell hardness specification ensures reliable feeding and minimal leading in your .40 S&W or 10mm autoloader while keeping rounds affordable enough for regular range work and serious practice.
Whether you're a precision pistol competitor fine-tuning loads for match day or a defensive shooter putting rounds downrange for proficiency, SNS cast bullets give you the consistency to dial in your accuracy. The flat-point profile and hardness spec work well across a range of 10mm and .40 handloading applications. Polymer coating protects the bullet during handling and feeding, and helps reduce barrel fouling compared to bare lead alternatives.
Reloaders choose SNS for the balance of quality and value—these aren't the cheapest cast rounds on the shelf, but they're far more economical than jacketed alternatives while delivering the uniformity you need to develop tight groups. With 500 rounds per box, you've got enough to develop a load, verify it at the range, and build a working inventory for practice or competition.
| Caliber | .40 Cal/10mm |
| Bullet Diameter | .401" |
| Weight | 180 grains |
| Profile | Flat Point (FP) |
| Box Count | 500 rounds |
| Alloy Composition | 92% lead, 6% antimony, 2% tin |
| Brinnell Hardness | 18 |
| Coating | Polymer |
| Manufacturer | SNS Cast Bullets |
Yes. SNS cast bullets are designed for .40 and 10mm handloading. The 18 Brinnell hardness specification and polymer coating are engineered to minimize leading and feeding issues in autoloaders, though as with all cast ammunition, you should follow published load data and safety practices for your specific firearm and powder charge.
The .401" diameter is the standard for .40 S&W and 10mm handloading. This size ensures proper fit and function in typical .40 and 10mm chambers. Always verify that bullet diameter matches your firearm's specifications and your load data before reloading.
Cast bullets are significantly more economical than jacketed alternatives, making them ideal for high-volume practice, load development, and range training. SNS cast rounds deliver the accuracy and consistency you need without the premium cost. The polymer coating also helps reduce barrel fouling compared to bare lead.
Each box contains 500 bullets, giving you a substantial supply for developing loads, testing, or building an inventory for regular practice and training.
