Lehigh .355 cal 9mm Xtreme Penetrator 115gr Bullet 100/rd

The Lehigh .355 caliber 9mm Xtreme Penetrator 115 grain bullet delivers deep, straight penetration with consistent terminal performance in 100-round quantities. Built on Lehigh Defense's monolithic fluid transfer design, this ammunition component offers ballistic characteristics specifically engineered to exceed the permanent wound cavity diameter of conventional expanding projectiles while maintaining predictable trajectory and velocity downrange.

The progressive nose geometry creates a unique damage profile: controlled penetration depth without fragmentation or unpredictable deflection, even through heavy intermediate barriers. At 115 grains, this projectile balances velocity retention with recoil management across common 9mm handgun platforms—critical for accuracy during repeated fire cycles. The monolithic construction eliminates lead-core separation, ensuring consistent weight retention and performance shot-to-shot across a 100-round box.

Operators and serious handgun trainers select the Xtreme Penetrator line for duty-grade ammunition development, precision load development, and field training where terminal performance verification matters. The 115-grain variant works across standard 9mm reloading and factory ammunition platforms, making it suitable for law enforcement training, defensive carry ammunition assembly, and competitive shooting protocols where barrier-blind penetration is a documented requirement.

Lehigh Defense continues to innovate beyond conventional bullet design, addressing terminal performance gaps that flat-nose and hollow-point designs cannot reliably solve. The Xtreme Penetrator Fluid Transfer Monolithic (XP FTM) architecture represents a shift toward physics-based ballistics rather than energy-dependent expansion, making it a preferred choice for shooters prioritizing consistent penetration depth and permanent cavity creation across variable defensive scenarios.
