The Lee Sizing Kit in .454 inch (Lee Precision part no. 90056) lubricates and sizes cast bullets to a consistent .454-inch diameter, the common cut for 45 Colt and similar big-bore revolver cartridges. It threads into any standard 7/8×14 reloading press, feeding bullets through nose-first so no special punches are required. Gas checks seat and crimp automatically in the same pass, and finished bullets collect in the kit’s dedicated container rather than scattering across the bench. Reloaders casting their own big-bore bullets use this kit to bring mold output to a uniform diameter before loading.
