How to Swage Bullets Using The

FRBL-6-M, -S, or -H Die Set

Type -H dies fit into the ram of the Corbin Mega-Mite press (CSP-2), Corbin

Hydro, Jr., (CSP-2H) press, and the Corbin Hydro-Press (CHP-1). The type -M

dies fit either the horizontal Silver Press (CSP-3) or the vertical Series II Press

(CSP-1). The type -S dies fit only the Series II Press (CSP-1). The last letter, -

M, -S, or -H, describes the outside diameter, threads, punch lengths, and which

presses the die set will fit. If a tool fits both the -S and the -M systems and

there would be no difference in it for either of them (such as punch holders or

draw dies), then the -M designation is used.

The set consists of a CORE SWAGE (CSW-1), a standard flat base CORE

SEATER (CS-1), a BOAT-TAIL PREFORM (BT-1), a REBATED BOATTAIL

internal punch for the CS-1, a POINT FORM (PF-1) die with both RBT and FB

external punches, and a LEAD TIP FINISHER (LT-1) die, which uses the same

external punches as the PF-1.

An EXTERNAL PUNCH is held in the FLOATING PUNCH HOLDER (FPH-1-

M or FPH-1-H), which comes with the press and screws down into the top

plate of the press. For the -M and -S external punches under 3/8-inch caliber,

a threaded bushing and steel ring are removed from the bottom of the punch

holder, placed over the external punch, and then screwed back into the bot-

tom of the punch holder to secure the punch. The punch holder screws into

the press head, so the punch faces the ram. For -M and -S punches from 3/8-

inch up, the bushing and ring are part of the punch assembly. For -H external

punches, only a threaded bushing is used, without the steel ring. The external

punch is the TOP punch in these systems.

The die screws into the press ram, with its INTERNAL PUNCH inside the

ram. Some internal punches require the use of spring powered retraction: for

the PF-1-H die, the internal punch is called an EJECTION PIN punch, and it

will have a quarter inch diameter hole through the head portion, through which

a 1/4-inch diameter retraction pin fits. The pin goes below the large spring

around the press ram, and pushes down on the pin, which then pushes the

punch down when the ram is raised, making it easier to insert material into

the die. For the PF-1-M and PF-1-S dies, a notch is machined into the head of

the internal punch, which matches a removable pin with knurled head pushed

into the front (CSP-1) or top (CSP-3) of the press. This is the STOP PIN. It

presses on the tail all punches except for the ejection pin punch, to cause

ejection on the down stroke. Because the PF-1 die would form the bullet around

this pin if the pin were allowed to remain in the die cavity during swaging, the

stop pin must be put into the notch and used to keep the pin retracted from

the cavity during swaging, holding it firmly during the down stroke to cause

ejection of the bullet.

In the -H system, a knock-out or ejection bar goes through a slot in the press

ram, below the spring and also below the retraction pin (if one is required

not all punches have a hole through the head). The knock-out bar supports

the head of the internal punch while the component is being swaged, and

comes to rest on the press mounting plate on the downward stroke. This stops

the movement of the bar while the ram continues down, making the punch

stop moving while the die goes down with the ram.

1. Core Swage Die - makes lead core. This is

always the first step with any style.

2. BT-1 Die - seats core into jacket, forms

start of rebated base on jacket. This step

is skipped with FB bullet styles.

3. Core Seat or BT-2 Die - finishes RBT using

RBT internal punch, or seats core for FB

bullets using FB CS External punch (5).

4. Point Form Die - shapes ogive on bullet,

using either RBT external punch, or FB

external punch (6) to match bullet.

5. Lead Tip Finishing Die - shapes lead tip or

pushes open tip closer together.

6. RBT Internal punch for CS-1 die, used only

when you want to make RBT bullets.

Never try to swage a component that will not go into the die by hand. The swaging operation depends on each component being slightly smaller than the die bore, and increases the bullet diameter a little with every step. The core seating die and point forming die are matched to each other for a given jacket and core material to within 0.0005 to .0010 inches with the core seater being smaller. The first die is the CORE SWAGE (CSW-1). It is used to form a piece of lead to precise diameter, length and weight.
