Lehigh Defense Xtreme Penetrator Bullets - 40 S&W/10mm Auto, 140 Grain Solid Copper, Lead-Free (400 Diameter)$67.00
Availability: In Stock
Lehigh Defense Xtreme Defense 40 S&W/10mm 115 grain solid copper lead-free bullets are engineered for handloaders who demand serious barrier-blind performance without the toxicity of traditional lead cores. Built from machined solid copper rather than plated or jacketed construction, these 400-diameter projectiles deliver the terminal characteristics serious defensive and hunting loads require—all in a lead-free platform that works in ranges with environmental restrictions and keeps your bench cleaner.
The Xtreme Defense design uses progressive nose geometry and radial flutes that direct hydraulic energy inward, building pressure to force a massive permanent wound cavity without relying on expansion. That geometry also minimizes surface area to concentrate force at the point of contact, giving you cutting edges that won't be defeated by intermediate barriers—bone, heavy clothing, drywall, or vehicle glass. The result is consistent performance regardless of what's between you and target, a characteristic that sets solid-copper rounds apart from conventional expanding designs.
At 115 grains, these bullets are sized for the 40 S&W and 10mm Auto platforms, making them ideal for reloaders building full-power defensive or hunting loads in either caliber. The solid-copper construction is inherently lead-free, so there's no concern about lead exposure during handling, sizing, or bullet seating—a real advantage if you shoot frequently or reload in shared facilities. The machined construction and design philosophy behind Xtreme Defense make these bullets a serious choice for anyone prioritizing terminal reliability over conventional expansion.
| Caliber/Diameter | 40 S&W/10mm (400 diameter) |
| Weight | 115 grains |
| Material | Solid copper, lead-free |
| Quantity Per Box | Not specified |
Yes—the 400-diameter sizing accommodates both calibers. Handloaders should use appropriate load data and bullet seating depths for each cartridge to ensure safe, reliable performance.
Lehigh Defense Xtreme Defense bullets don't rely on expansion. Instead, the progressive nose geometry and radial flute design create a permanent wound cavity through hydraulic energy and sharp cutting edges. This approach performs consistently regardless of what the bullet passes through before reaching soft tissue—a key advantage for barrier-blind defensive scenarios.
Yes. The solid copper construction means no lead core or toxic materials, making them suitable for indoor ranges with environmental restrictions and reducing your exposure during handling and reloading.
Always consult published load data specific to the Lehigh Defense Xtreme Defense 115-grain bullet in your intended caliber (40 S&W or 10mm). Load data varies by powder type, primer, and brass, and following established safe loads is essential for reliable performance.
