Lee Classic Bullet Sizing Kit, .311

The Lee Classic Bullet Sizing Kit for .311 (Lee part no. 90039) lubricates and sizes cast bullets in one pass, then seats and crimps gas checks on the same stroke. Lee builds this kit around a standard 7/8-14 thread sizer die, so it threads into any single-stage press without an adapter. It is intended for cast bullets sized to .311, giving cast-bullet casters a repeatable way to bring bullets to exact, uniform diameter before loading. This is a lube-and-size tool, not a lubricant or press by itself; Lee sells those separately. Find it filed with our reloading equipment selection.
