The Lee Sizing Kit in .427 inch (Lee Precision part no. 90053) lubricates and sizes cast bullets to a uniform .427-inch diameter, a common cut for medium-bore revolver cartridges. It threads into any standard 7/8×14 reloading press, pushing bullets through nose-first with no special punches required. Gas checks are seated and crimped automatically in the same stroke, and finished bullets are captured in the kit’s dedicated container. Reloaders casting their own bullets rely on this kit to correct mold variation and keep every bullet at the same diameter before it reaches a case.
