I picked up a Lyman 45 sizer that had an interesting mod to the sizing die,
someone had drilled a hole all the way through the die and cut a groove on the top of the push out rod. this lets the lube under the bullet have a way to escape, when you size the next bullet the lube buildup will just get pushed out through the die then along the groove, better have a catch box or you will have lube all over the floor.
i have not tested this out yet as i am in the process of rebuilding the sizer and the die is a .454 and i do not have any guns that use that size bullet
