Lehigh Defense Xtreme Defense 10mm Auto 150gr Fluid Transfer Monolithic - 50/Box

The Lehigh Defense Xtreme Defense 10mm Auto projectile is a 150 grain Fluid Transfer Monolithic (FTM) bullet purpose-built for self-defense handloading. Machined from a single piece of solid copper, this lead-free projectile is engineered to drive through barriers without deformation or trajectory change, then transfer energy aggressively into soft tissue on impact, producing a large permanent wound cavity.

The Xtreme Defense design uses Lehigh's proprietary FTM tip, which initiates fluid transfer the moment it contacts soft tissue, generating a rapid threat-stopping energy dump while preserving the bullet's mass for deep, straight penetration. The .400" diameter bullet is sized to match the 10mm Auto case mouth, and the .153 ballistic coefficient with .134 sectional density gives reloaders predictable, repeatable performance across common 10mm Auto defensive platforms.

Each box contains 50 solid copper projectiles for hand-loading only; they are not loaded ammunition and are intended to be paired with the reloader's preferred brass, powder, and primer to build 10mm Auto carry or home-defense loads with barrier-blind performance and reliable deep penetration.
