Underwood Maximum Expansion 40 S&W Ammunition 140 Grain Solid Monolithic uses Lehigh’s Maximum Expansion Technology to produce projectiles engineered to create the largest wound channels available. These advanced hollow points are designed to expand upon contact with fluid-based mediums using hydraulic energy, while remaining unchanged when striking dry materials like wood, drywall, bone, or sheet metal. The Maximum Expansion bullets deploy razor-sharp petals at the widest diameter, maintaining an optimal cutting surface for maximum impact.
Each box contains 20 rounds loaded with monolithic bullets, delivering a muzzle velocity of 1050 ft/s and muzzle energy of 343 ft-lbs. The nickel-plated brass casings offer multiple advantages, including smoother feeding in all firearm actions, enhanced corrosion resistance compared to standard brass, improved aesthetics, and easier cleanup for reloaders. All Underwood Ammo rounds are loaded with flash-suppressed powder to preserve vision in low-light conditions, ensuring readiness if a situation demands it.
