Please note that these are bullets (projectiles) only for reloading. This product is not loaded ammunition that is ready to use in a firearm.

Our Maximum Expansion® Technology is used to produce projectiles that create the largest wound channels of any bullet on the market. 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 handgun and subsonic rifle 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 bullets shank once again reducing the diameter down to a less effective size. The maximum diameter expansion limits penetration making the handgun Maximum Expansion bullets ideal for situations where over penetration can endanger innocents.
