Corbin Pound Die PD-1
The Corbin Pound Die makes swaged lead bullets without a press, using a 5 pound plastic, leather, or lead faced
mallet to supply the driving force. The die consists of five parts:
1. Base
This is the largest diameter cylinder. It is machined so
that the die and base punch both fit into its cavity. One end of
the die body is machined to mate with the largest diameter hole

in the base. The base holds the die and base punch during
swaging, and then the base punch is removed and the die put
back again to push the bullet out.
2. Die
This is the cylinder with one smooth, machined end that
mates with the largest diameter hole in the base. The other end
is slightly funnel-shaped. The base punch fits up inside the flat
end of the die, and is put inside the base during operation. The
nose punch is the shorter of two identical shaped punches,
which is put into the funnel-shaped end of the die to swage the
bullet.
3. Base punch
This is a large diameter knurled cylinder with a short stub
of a punch projecting from one end. It fits inside the base (large
end) and inside the die (small or punch end). The shape of the
base punch determines the shape of the bullet base. This punch
is put into the die for swaging, then removed for ejection of the
bullet.
4. Nose punch
This is the shorter of two identical shaped punches, which fits into the
slightly funnel-shaped end of the swage die. It is struck with a plastic, leather,
or lead faced mallet to apply force to the lead and swage a bullet. Then it is
removed, and the ejection punch inserted in its place. The base punch is
removed, and the ejection punch is lightly struck to
push the bullet out of the die and into the base. The base is then picked up to release
the bullet.
5. Ejection punch
This is the longer of two identical shaped punches. It fits into the die to push
the finished bullet out the other end. It is not to be used for swaging, because it would
be too easy to strike such a long punch off center and bend it. Use only the shorter
punch for swaging! Use the ejection punch only with very light pressure to push the
bullet out of the die.
This die is used with soft lead, Bhn5, and Corbin Swage Lube lightly applied to the
lead core before swaging, for best results. Never strike the nose punch without a piece
of lead in the die of sufficient length to prevent the nose punch edge from contacting
the base punch. Lead cores can be cast using the Corbin CM-4 Core mould, up to .365
diameter, and the Corbin CM-3 Core mould, from .365 to .50 inch diameter. The
material put into the die should always fit easily before swaging, never forced in.
