Lee Precision Undersize Sizing Die 45 ACP

Lee Undersized Carbide Sizing Dies are perfect for reloaders who want exceptional feeding reliability in their handguns. These dies undersize brass between .002″ and .003″ smaller than other Lee Carbide Sizing dies. Ammunition with undersized brass cases provide more reliable chambering when fed from a magazine. Competition shooters rely on having ammunition that will feed and chamber each round of ammunition as it is stripped out of the magazine. One of the other benefits reloaders have reported when using Lee Undersized dies is increased consistency and accuracy in loaded rounds because these dies help increase and provide more consistent neck tension on bullets. The solid carbide insert inside of these dies is ground to a special contour that does not leave a belt mark on the case. These carbide dies do not require lubricant while resizing, though a little case lube will make the sizing process easier. Shellholder sold separately.
