this is the first draw die im making for the RCBS Rock Chucker model presses to draw bullet jackets. im just showing what im planning to do. https://www.youtube.com/watch?v=JfHyQkOxuOM
but as you can see the holder for the jacket blank has 2 purposes, one is to hold the copper slug centered in the die and the other is to act as a guide for the drawing punch to keep it centered in the die. the blank holder/guide will be spring loaded when everything is finished.. all the other dies and punches will end up the exact same way..
this will screw up from the bottom of the die hole and the drawn cups will be pushed up and through the top of the press. the die will be back bored a little larger than the drawn cups so they do not bind up and they are easier to remove..
but all i have to do with this die is cut the bevel where the jacket is drawn, thread the die, back bore it, heat treat the setup, and then polish it and then this die will be finished...
im still curious as to why nobody makes jacket drawing dies for the larger reloading presses. i know that Corbin makes a jacket reducing die but not a entire drawing setup for the reloading presses. i know most presses only have the smaller 7/8 hole in the top and that would limit them a lot..
