Lee's Lube & Size Kit allows you to lubricate and size cast bullets. It can also seat and crimp gas checks. Intended for use on single stage presses only, the sizer die has standard 7/8x14 threads. Bullets are pushed through the sizing die nose first, so no special nose punches are needed. (Push through punch is used in place of a shell holder in the ram.) Sized bullets are captured in a special container. For cast bullets, select a sizing kit to be .001" larger than groove diameter. Kit contains sizer box, sizer punch, and sizer die, and instructions. NOTE: Lee Liquid Alox and press sold separately.
