The Lee Sizing Kit in .278 inch (Lee Precision part no. 90261) sizes cast bullets to a consistent .278-inch diameter, a cut used by certain 7mm-class rifle bullet molds. It threads into any standard 7/8×14 reloading press, pushing bullets through nose-first so no special punches are required. Gas checks seat and crimp automatically as part of the same operation, and finished bullets are captured in the kit’s own container. Reloaders casting their own bullets use this kit to correct mold variation and keep every bullet the same diameter before it reaches a case. Lee lube is sold separately.
