Lehigh Defense 9mm 118 Grain Maximum Expansion Brass Pistol Ammo 20 Rounds. Lehigh Defense Maximum Expansion technology is used to produce projectiles that create the largest wound channels of any bullet on the market. For optimal accuracy with Lehigh Defense bullets it is important to clean the bore of all non-Lehigh Defense copper fouling prior to shooting Lehigh Defense bullets. Copper fouling in the bore that has been deposited from the use of common cup and core bullets will have a substantial negative effect on the accuracy of Lehigh Defense solid copper bullets.
