Underwood .40 S&W 140 Gr. Lehigh Defense Maximum Expansion- Lead Free- Box of 20

Lehigh’s Maximum Expansion Technology is used to produce projectiles that create the largest wound channels of any bullet you can buy. These cavernous hollow points are designed to expand upon contact with a fluid-based medium through hydraulic energy. They do not expand on dry mediums like wood, drywall, bone, or sheet metal. The expansion process of Lehigh’s Maximum Expansion technology is very different than that of a traditional lead jacketed bullet that expands when it comes in contact with a hard surface. We designed these bullets to expand where the expansion is needed and that is in the vital zone of your intended target. Lehigh Maximum Expansion bullets expand with razor-sharp petals positioned AND maintained at the largest diameter to provide the greatest cutting surface. Contrast this with a traditional jacketed bullet that expands and quickly mushrooms the nose back along the bullet shank once again reducing the diameter down to a less effective size.

Nickel-plated casings, our nickel plating process provides several key benefits, not limited to but including; improved feeding in all actions of firearms enhanced corrosion resistance over traditional brass, improved cosmetics, and ease of cleanup during reloading. Nickel-plated casings will not tarnish like brass during storage or when in contact with foreign materials such as leather, moisture, and other metals.

As with all of Underwood Ammo rounds, they utilize flash suppressed powder so that your vision will not be compromised if it becomes necessary to use your firearm in low light. This ammunition is new production, non-corrosive, in boxer-primed, reloadable brass cases.
