Take a LARGE nut, and putting it in a lathe bore it out to size your hulls, then take a LARGE long socket or piece of pipe and position the nut next to it. Take Imperial sizing wax and lube the cleaned brass hull, then using a shop vise push the hull into the
sizing nut, Mine has a cut out for the rim to seat flush in the nut.
Take the nut and secure it in or on top of the vise and drive the hulls out with a rod that has a recess for the primer bump inside the hull.
