Lehigh Defense Xtreme Penetrator bullets for 40 S&W and 10mm Auto deliver a distinctive approach to handgun ammunition design. Built from solid copper and engineered lead-free, these 140-grain projectiles use a progressive nose geometry with radial flutes that manage energy transfer through barriers and into soft tissue. Whether you're reloading for self-defense, hunting, or specialized applications, the Xtreme Penetrator's monolithic construction means you get deep, straight-line penetration coupled with a wound cavity that significantly exceeds what conventional round-nose or flat-point bullets produce—without the unpredictable degradation that hollow points sometimes suffer when passing through intermediate barriers like heavy clothing or drywall.
The engineering behind these bullets centers on controlled hydraulic dynamics. As the projectile encounters resistance, the flute design forces energy inward, then accelerates it outward in rapid succession, creating pressure spikes that damage tissue well beyond the bullet's path. The result is reliable penetration depth and a permanent wound cavity typically two to four times larger than traditional non-expanding designs, often matching or exceeding the performance of conventional expanding rounds. Because the Xtreme Penetrator is all solid copper, it's both environmentally responsible and resistant to the fouling and consistency issues that can arise with softer alloys.
These are unprimed, unfired handgun bullets ready for your reloading bench. The 400-diameter specification matches standard 40 S&W and 10mm Auto dimensions. Lehigh Defense's solid-copper monolithic design has become a go-to choice for reloaders who prioritize barrier-resistant performance and consistent terminal effect without the environmental concerns of lead-core ammunition.
| Caliber | 40 S&W / 10mm Auto |
| Weight | 140 grains |
| Diameter | .400" |
| Material | Solid copper, lead-free |
| Type | Monolithic (XP FTM design) |
| Form | Unprimed, unfired bullets for handloading |
Yes—these are standard .400-diameter bullets designed for both calibers. They're unprimed and ready to load on your press. Consult your reloading manual for the correct powder, primer, and case specifications for your cartridge.
The Xtreme Penetrator uses a different approach: instead of relying on expansion, the radial flute design creates tissue damage through rapid fluid transfer and cavitation. The result is a wound cavity comparable to or exceeding quality hollow points, with the added advantage of consistent performance even if the bullet passes through intermediate barriers like clothing or drywall.
Yes. Lehigh Defense Xtreme Penetrators are manufactured from solid copper and contain no lead, making them suitable for use in lead-free shooting areas and compliant with environmental regulations in states or ranges with lead ammunition restrictions.
The distinguishing feature is the progressive nose geometry and radial flute design unique to the XP FTM (Fluid Transfer Monolithic) line. This engineering creates high-pressure spikes and cavitation that generate a larger permanent wound cavity than standard monolithic designs, while maintaining deep penetration regardless of barriers encountered.
