Lee Precision Undersize Carbide Sizing Die Features The Lee Precision undersize sizing die is machined .003 smaller than the company s standard carbide sizing die giving reloaders a solution for brass that resists chambering after a normal resize. This tighter dimension is particularly useful for reloaders experiencing chambering issues in tight-chambered .45 ACP pistols or those loading brass that has been fired multiple times. Carbide construction means no case lubrication is required during sizing simplifying the reloading process and reducing cleanup time. This single die is sold alone allowing reloaders to add it to an existing die set as needed. Consistent case sizing is critical to reliable chambering and accurate ammunition and this undersize die addresses cases that a standard die leaves slightly oversized. Lee Precision has built a reputation for affordable functional reloading equipment trusted by handloaders for decades. Adding this die to a .45 ACP reloading setup provides an extra layer of insurance against chambering problems in competition or defensive ammunition. For reloaders seeking a dependable undersize sizing solution this Lee Precision die is available for sale at GrabAGun.
