Underwood Ammo Maximum Expansion .40 S&W 140gr Solid Copper - Box or Case

The Underwood Maximum Expansion line brings Lehigh Defense solid copper engineering to a .40 S&W loading purpose-built for personal defense. These 140 grain monolithic projectiles are designed to open into a wide frontal diameter while still retaining the mass for dependable penetration.

Each round is loaded in nickel plated brass for smooth feeding, reliable extraction, and corrosion resistance. The factory-rated muzzle velocity of 1050 fps produces 343 ft lbs of energy at the muzzle, a manageable recoil package for both compact and full-size .40 S&W handguns. As a lead-free, solid copper projectile, this load is well suited to home defense, daily carry, and indoor training in jurisdictions with restrictions on traditional jacketed hollow points.

Underwood packages the Maximum Expansion in 20-round boxes, with the case configuration containing 10 boxes for 200 rounds total.

Your purchase options:

• Box - 20 Rounds
• Case - 200 Rounds (10 Boxes)
