Bullet Swaging Overview

Bullet swaging uses only pressure to form the projectile. Unlike bullet casting no heat is used. The bullet maker uses pressure to force bullet material into a die while one or two punches apply pressure to the bullet. The high pressure causes the material to flow and fill out the shape in the die. Then the bullet is ejected from the die and is ready to use.

There are a great many choices as to how the bullet can be swaged and as to what shapes, materials, and bullet types can be made. This can make swaging sound complicated and difficult but it really is simple once the basics are understood.

First sort and clean the cases.  Make certain all of the primers are fired.  Cases can be washed with hot water and dish soap or tumbled in a non-abrasive media to clean them.  Next put the neck expander die in the top of the Walnut Hill press.  The reloading adapter with a RCBS #45 or a 25 ACP shellholder will be in the press ram.  With the ram up, set the expander die so that it almost touches the shellholder.  Lightly lube the inside of a case neck and put the case in the shellholder.  Raise and lower the press ram to expand the case neck.

Now using a propane torch or other heat source heat the case head to a dull red.  A coating on the cases will turn black and burn off.  The cases can air cool once heated.

The cases will now be resized using the sizer die and draw punch.  Cases should be lubed with Bullet Maker’s Lube.  When resized the lead cores are seated using the punch included in the die set.  Then the bullets can be pointed up in the point forming die.

Cartridge cases are fine for making 30 to 312 caliber plinking and light game bullets but for best accuracy commercial drawn cases should be used.
