RCBS Lube-A-Matic Bullet Sizing Die, .310-inch

The RCBS Lube-A-Matic Bullet Sizing Die in .310-inch (RCBS part no. 82213) sizes cast lead and gas-check bullets to a precise, consistent diameter before they go into a loaded round. It is built with a hardened steel interior that holds true, round alignment through repeated cycles instead of wearing oval over time. The die drops straight into an RCBS Lube-A-Matic two-die sizer/lubricator or a Lyman 450/4500 lube-sizer, so cast-bullet reloaders already running one of those presses can add calibers without buying new equipment. For anyone who casts their own bullets for handgun or rifle loads, this die is the fast way to bring every bullet in a batch to the same finished diameter.
