Corbin Type-R dies fit into a standard 7/8-14 TPI reloading press head. The external punch fits into a standard RCBS style shell holder slot in the ram. Not for use on light duty turret presses,
or those using universal shell holders instead of the T-slot ram, the type -R dies are an inexpensive way to get started in bullet swaging. Made in a 6-S ogive shape for .224 caliber, for jacketed rifle bullets with up to four dies per set. These include the CORE SWAGE, CORE SEAT, POINT FORMER, and LEAD TIP FORMER dies. The BSD-2-R set is the minimum required to make a rifle bullet, using a jacket (either commercial or drawn from a fired .22 case with the RFJM-224R die) and scrap lead (cast to fit the jacket ID in a CM-4 core mould) or lead wire (cut to length using a PCS-1 core cutter). A kit consisting of a jacket maker die, core seater, point former, swage lube, core mould and handbook, called the KIT-224R, makes it easy to purchase of all the correct items for making free 224 bullets from fired 22 cases and scrap lead.
PRO-SWAGE dies, Corbin PRO-1-R, are available in a single-die set that makes a soft lead, gas check, Base Guard, half-jacket, or 3/4-jacket bullets in calibers from .35 to .500. The most popular two styles of Pro-Swage are (1) Paper Patched Rifle, with a 1-E (1-caliber long elliptical ogive) nose, and a cup base, and (2) Base Guard Pistol or Rifle, which uses your choice of standard SWC nose plus the Base Guard disk base.
The ADVANTAGES of the -R dies over other types are:
The DISADVANTAGES compared to using dies for a Corbin press are:
- You don't need a special swaging press, but can use any sturdy single station reloading press that accepts standard RCBS type shell holders, and has a 7/8-14 tpi head.
- You can swage up to 58 caliber soft lead bullets using the PRO-SWAGE die.
- -R dies are three times slower to operate (since the reloading press holds the die with the mouth down, like a reloading die, and has no built-in ejection system)
- -R dies are limited to soft lead only to avoid breakage (224 and 243 may use wheelweight up to Bhn 8-10 with care).
- -R dies are only made in stock shapes and diameters (because custom work would cost the same as getting the faster, more versatile Corbin press/dies). Pro-Swage dies are basically core seaters, which must form a bullet with a .015-.020 shoulder between ogive and shank, in the semi-wadcutter style.
- Reloading presses usually have no bearings, use soft steel rams, and are designed with about a 4-inch stroke instead of 2-inch, so they do not provide the leverage, speed, or precision of a swaging press.
Corbin -R dies have been sold for nearly three decades in a 224 KIT, which converts fired .22 LR cases into extremely good quality yet highly explosive jackets, then forms these into accurate
varmint and target bullets. The result is a virtually free and unlimite supply of .224 diameter bullets! The kits include a core mould (4-cavity adjustable weight that does not need handles)
and a jacket maker die (to turn 22 fired cases into jackets), a core seater and point forming die to make the bullets, 2-ounce bottle of Corbin Swage Lube, and the Corbin Handbook of Bullet Swaging.
Production rate is typically 60-100 bullets per hour, starting from empty fired .22 cases and
scrap lead. To use the kit, you would need a lead pot or other way to melt the scrap lead and pour
it into the adjustable weight core mould (which makes four little cylinders of lead and ejects them
straight out the top of the mould). If you do NOT want to use scrap lead, Corbin has spools of lead wire in the correct (.185-inch) diameter, and a PCS-1 Precision Core Cutter to snip off exact lengths of wire for bullet cores. A 10-pound spool of wire can make upward of 1,850 bullets depending on the bullet weight. In larger calibers, more lead is used, so
the number of bullets per spool of lead goes down (weight is constant, so there is less length in a spool of larger diameter wire).
Precision of the bullets made with type -R dies is only slightly less than that of bullets made
on Corbin's high precision swaging presses. The dies are limited by the tolerances in the alignment
of typical reloading presses, which do not use any bearings and are usually not very closely honed
between the threaded head and the ram. The more precision or elaborate styles of bullets, such as
rebated boattails, require dies that are not made in the -R die system for this reason. However, as
a low cost way to become familiar with swaging, the reloading press swage dies have served thousands of shooters for generations!
The Corbin Silver Press is a discontinued model that was replaced by the more powerful and versatile S-Press. The Silver Press is similar to the Mity Mite press originally developed by SAS dies and produced by Corbin in the early 1970s. It was a horizontal stroke swaging machine that did much to popularize the concept of home bullet making and custom bullet making as a cottage industry.
The CSP-3 press only used type -M dies, which were 3/4-inch diameter but had a
5/8-24 threaded tendon to fit the ram. The press design was such that the ram and die moved back into the cast frame on the back stroke, so a larger die could not be put into the ram. The CSP-1 S-Press used a system where the die did NOT retract into the frame of the press, so nearly any size die could be used. Both type -M and type -S (1-inch OD) dies screw directly into the ram of the CSP-1 press.
The CSP-3 is shown only for reference and historical value. Books and printed literature discussing this press should be regarded as obsolete historical information. Parts are kept in stock for repair of existing Silver Presses. Any new purchase of an entry level swaging press should be the CSP-1 S-Press, which has a number of advantages and would cost no more to build today.
The S-Press press is twice as powerful as the largest cast-frame reloading presses, with more than five times the breaking strength. Corbin -S or -M series dies fit into the press ram, with automatic ejection on the down stroke. You can also use standard 7/8-14 TPI loading press dies in the S-Press. This is our MOST versatile hand press, and the one we recommend for serious handloaders and prototype designers. Special powder coat finish is impervious to most chemicals, heat, salt air, and abrasion. If you are interested in starting your own swaging business at minimal cost, this would be the correct press to consider.
The CSP-1 was designed as a combination swaging and reloading press, with the emphasis on power, strength, and alignment. It is a commercial grade product that has found a home both in industry and in the well-equipped hobbyist's shop. Because it can use the special type -S die with a 1-inch diameter body and a thrust-bearing shoulder in its hardened alloy steel ram, the S-Press has the ability to use harder lead. It can handle alloys up to Bhn 8-10 depending on the caliber and complexity of the shape. Blunt shapes in smaller caliber can accept harder material and still produce a good bullet, whereas sharper pointed shapes in larger calibers take a great deal of force even to flow soft lead.
The S-Press works with older -M dies and with pre-2002 S-Dies which have a slotted ejection punch head. The 2002 and later version of the S-punch uses a larger diameter head with a hole completely through it. The stop pin, in the front of the press, is different depending on which kind of die is to be used. Older dies with a slotted punch use the SHORT pin. Newer dies with a hole through the punch head use the LONG pin. The LONG pin provides for support on both sides of the ram, and is more than 200% stronger than the earlier method of ejection. While the short pin MAY be used with the newer style ejection punch, it does not provide as much support and protection against bending as the new, longer pin.
This press uses four precision roller bearings in the links. The ram moves inside two inch-long oil-impregnated bushings. The toggle linkage moves inside a high pressure bearing in the tail of the ram. No moving parts, in fact, are without a bearing in this press design, whereas few other presses have even one bearing.
The frame of the CSP-1 press is machined from steel. Consequently, it is considerably smaller than cast iron presses with less than a fifth of its power and one third of its strength (or less).
An optional floor stand (CSP-S) and a foot-high steel bench stand (CSP-B) are offered to put the press at a comfortable level for long production runs. It can also be mounted directly to the top of your reloading bench. The press comes with a floating punch holder for the external (top) punch, a reloading adapter to hold RCBS shell holders with a spring/ball bearing detent, a primer catcher tray that slips over the ram and catches spent primers when the press is used for reloading, and instruction book. Any type -M, type -S or type -R die can be used in this press. When possible, it is better to use the type -S (for strength).
The Corbin Hydro-Mite (CSP-1H) is a hydraulic version of the CSP-1. It uses type -S dies.
The same capabilities for caliber, lead hardness, length, and other parameters apply to both the hand and the hydraulic versions, but the Hydro-Mite has these advantages:
- Tireless operation. You or your employee can run it all day by pressing a button.
- Same power at the start of stroke as at the end. Drawing operations are easier.
- Remote control. A long control cable lets you sandbag the press for pyrotechnical work.
We do not suggest that most handloaders can or should become involved with explosives, tracers, or other chemical special effects, but if you are already involved and know what you are doing, this press can provide an additional margin of safety to your work. When the ram goes up and the material is compressed, you have the ability to be behind a barricade with the controls in your hand.
The CSP-1H can be provided with either 110-120 volt 60 Hz, 220-240 volt 60 Hz, or 240 volt 50 Hz motor of 3/4-HP, single phase. The press has a stroke emulating the full length (reloading) stroke in the regular CSP-1, but with full swaging power. It can be used for both jacket drawing and swaging, as well as reloading.
Care must be taken to adjust reloading dies properly! It is possible to flatten a reloading press die if you misadjust the die position and then run the ram up under full power. Always run the ram up first and then install and adjust the die with the ram at maximum extension.
The CSP-1H Hydro-Mite Press uses a high quality, industrial grade hydraulic power unit equipped with remote operation solenoid valve controls. The power unit connects to the press assembly with two flexible hydraulic lines, each of which has instant disconnect fittings (self-closing). It is a relatively quiet unit, such that a normal conversation can be held while it is running, and it is unlikely to bother anyone in the next room if operated at night.
With a 2-inch, 4-inch and 6-inch triple stroke, the Mega Mite (CSP-2)
is suitable for reloading up to .50 caliber MG as well as swaging bullets
from .224 to .458 caliber.It accepts type -H dies in a 1-inch by 12 TPI ram, and a large floating punch holder FPH-1-H or reloading adapter bushing in the 1.5-inch
by 12 TPI head.
Originally designed as a helper press to go along with the powerful Corbin Hydro-press (Model CHP-1) and use the same dies and punches, the CSP-2 is often used as the sole press for a prototype or custom bullet shop. It is the ultimate
hand powered reloading and swaging press; nothing larger in size offers anything greater in power and strength, since most large presses have been built with 40,000 psi to 80,000 psi cast iron frames and no bearings. The CSP-2 utilises alloy steels in its frame tha can handle upward of 120,000 psi, and moving joints that operate inside heavy duty bearings, either roller or solid depending on the load requirements.
If you want to make bullets larger than .458 diameter, or harder than Bhn 8-10, this is the smallest press that will do the job. Large bullets may require a case-by-case analysis to determine if the press is suitable: some large diameters are easily formed because their length is suitable to the stroke, while others of the same or smaller diameter might be unsuitable because of the length of the ogive or complexity of the shape. Any compound leverage hand press generates its maximum power at the end of the stroke: if work is required earlier in the stroke, careful analysis of the available power curve is required. We do that for you, of course, and guarantee that anything we recommend will work. Many clients start a custom swaging business based on this press.
The CSP-2 Mega-Mite Press takes the type -H die, and comes with a reloading
adapter kit that
converts the 1-1/2 inch by 12 thread per inch head to 7/8 by 14 thread per
inch, extends the
ram and accepts regular RCBS button shell holders for reloading. A single
link pin can be moved to a new position to give you a long reloading stroke.
An optional SK-1-H Stripper Kit can be installed for rapid redrawing and trimming of bullet jackets (the die fits the press head, using the 1-1/2 by 7/8-14 bushing, and the punch fits the ram). Bearings are installed in the press head to guide the operating rods, and matching mount holes in the moving ram plate connect the rods to the moving ram.
An optional floor stand can be ordered with the press: the combination is catalog number CSP-2S. When ordered this way, the floor stand is discounted heavily. We recommend that you use the CSP-2 press on the stand, as it is very large (70-pounds) and may not be conveniently positioned
on most reloading benches.
The CSP-2H has the same power, stroke, and dimensions as the Hydro-press. It uses the same cabinet, but does not have the electronic timing, position sensing, and automatic pressure sensing features. It can be thought of as an economy model of the Hydro-press. There are certain operations, such as feeding copper strip automatically to the JMK-2-H jacket maker system, which can only be done on the Hydro-press, but many other operations can be done using the CSP-2H. The CSP-2H looks virtually the same as the CHP-1 Hydro-press except for the number of controls present on the top panel.
The main difference in operation between the CSP-2H and the CHP-1 are:
- CHP-1 can be set for automatic stroke cycles.
- CHP-1 uses precision electronic position sensors for ram travel.
- CHP-1 has interfaces for automatic strip feed jacket maker.
- CHP-1 uses a load position sensor for easier loading.
- CHP-1 has more versatile cycle controls.
- CHP-1 uses both position and pressure limit reversing.
- CHP-1 has ram speed control for the up cycle.
- CHP-1 has electronic dwell timing at top of stroke.
Otherwise, the same components are used in both machines. It is not practical to "convert" a Hydro Junior into a Hydro Press, as the labor would be more than the price difference to strip and rebuilt the hydraulic and electronic logic systems.
- CSP-2H ram only moves when you hold down the buttons.
- CSP-2H uses electric roller-type limit switches for ram travel.
- CSP-2H does not interface with other devices electrically.
- CSP-2H has top and bottom position sensors only, no load position.
- CSP-2H has a single, manual cycle controlled by position.
- CSP-2H has only position limit stop without auto reverse.
- CSP-2H uses constant full speed up and down cycle.
- CSP-2H uses manual button control for dwell timing.
The reasons for purchasing the CHP-1 instead of the CSP-2H would be:
Price is always a decision factor, of course, so if you cannot afford to invest in the Hydro-Press, your bullet making venture can still get underway with the Hydro Junior, and later it will be very useful to have a second press (when the orders are rolling in!).
- Faster over-all production rate because of the additional automatic cycle controls (which free the operator for longer times between strokes, to accomplish other handling tasks while the press operates: one operator can often run two CHP-1 presses, or one CHP-1 and another press such as the CSP-2H)
- Additional operations such as automatic feed for the JMK-2 jacket drawing accessories, which are not practical for the CSP-2H because it has no interface to control such accessories.
The world's most powerful bullet swaging press...
The Corbin Hydro-press is the world's most advanced custom
swaging system, with the ability to manufacture lead wire, jackets, gas
checks, base guards, bullets from .224 to 22mm, and to reload calibers
up to 20mm. It swages the hardest lead alloys in calibers from .224 to .512,
and can produce bullet weights to 1000 grains, lengths to 3 inches. The dies for this press are type-H. They also fit the Mega-Mite and Hydro Junior. Either of the power presses can make .50 caliber BMG bullets, which require too much stroke/cycle length ratio for any of the hand presses.
The Hydro-press weighs aproximately 350 pounds and can be ordered for
either standard USA 115-120 volt 60 Hz power, or the export version with 220-240 volt 50 Hz power. Power is furnished by a self-contained
1.5 HP motor, operating within the enclosed cabinet, which is forced-air cooled with two 100 cfm fans. Air expands through a narrow gap in the cover, over the lower portion of the cabinet,
which is an integral hydraulic fluid reservoir. The expanding air cools the tank and allows continuous production operation even in hot climates. The minimum ambient temperature
for running the CSP-1 is 60-degrees F, which is well within the normal room
A vast array of tools and dies are available for the Corbin Hydro-press,
including lead wire extruders, hollow lead tubing extruders, bullet swage dies of every imaginable type and size including those up to an inch in bore diameter (cannon shells and 4-bore slugs), jacket making tools that use either strip or tubing as the starting point, bullet and jacket redrawing dies, and much more. One interesting special die is the dual-diameter sizer, which can transform a regular bullet into one which has less friction in the barrel with the same or better guidance and at the same time eliminates jamming or tight bolt closure with short throated chambers and barrels.
The Hydro-press can be shipped by truck or air freight. It has been exported
every country not on the prohibited list for US sales, and is in use by
research and development firms, defense contractors, and private individuals

Paper patched or composite hard and soft lead two-part
bullets are easy to swage in a single die (if the bullet has a shoulder between nose and shank) or in two dies (for smoothly curved junction between the nose and the shank). The proper dies are type -H for the Corbin Mega-Mite,
Hydro-Press, and Hydro, JR. presses. Bullet swaging techniques are discussed and illustrated on Corbin's "Swaging" page.
