Lee Precision Bullet Lube and Sizing Die Kit .308 Diameter
The Lee Precision .308 diameter bullet lube and sizing die kit is one of the quickest and easiest ways to lubricate and size cast bullets. The sizing die that comes with the kit fits in any press that accepts standard 7/8"-14 threaded dies. Bullets are pushed through the sizing die nose first, so no special top punches are needed. Gas checks are automatically seated and crimped in place. Sized bullets are captured in the special container.
Lee recommends bullets be relubed after sizing to be sure the sized portion is coated with Alox (sold separately).
All lead bullets must be lubricated, but it is not absolutely necessary to size all cast bullets. Bullets must be sized if they are so large that they expand the case too much to freely enter the gun's chamber. Sizing sometimes helps accuracy by making the bullet uniform in diameter. Sizing helps ensure uniform start pressure and better accuracy. Gas checks can be installed with this tool. Simply place the gas check on the base of the bullet before sizing.
