THE T-MAG II PRESS
The Lyman T-Mag Press features a powerful
compound leverage with a unique position indexable turret and quick disconnect release system.
This allows you to mount several die sets, precisely locked in and ready to reload at all times.
You may also mount your powder measure in
one of the die stations if it is compatible with the
7
⁄8" x 14 threads (as many are).
The Lyman #55 Powder Measure can be
mounted to the turret using the Lyman
7
⁄8" x 14
Adapter.
A long steel handle adapted with a Ball type
knob adapts easily for left or right hand operations.
Mounting the Press
Remove the T-Mag Press from the packing box
and position it against the edge of your bench top in the most convenient location, usually
near the center of the bench, leaving a work area on each side of the press. Mark the position
of the mounting holes and drill them; then, using
3
⁄8" bolts and suitable washers and nuts,
securely anchor the press.
The toggle link mechanism and ram have been factory installed. Decide which mode of
operation you prefer - right or left hand - and install the handle in the appropriate mounting
hole in the linkage toggle. Be sure to thread the locknut onto the handle first. After the handle
is screwed into the toggle, lock it in place by turning the locknut to a jam-fit against the toggle surface.
NOTE: A positive stop built into the frame blocks handle travel after the ram has passed top
dead center. No further pressure should be applied, once the stop is reached, to prevent possible damage to the press.
Installation of the Shell Holder
The shell holder slides into the slotted top of the T-Mag
ram and is held in place by the integral spring clip.
To make the shell holder more accessible to your hand,
turn it slightly to the left if you are right handed; slightly to
the right if you are left handed. Most reloaders use their
strongest arm to operate the ram.
Extra shell holders are available for a wide variety of
cartridges as indicated in the current annual Lyman
Catalog.
Installation and Use of the Priming Arm
Open the package containing the Lyman Priming Arm.
It contains a priming arm complete with a large priming
sleeve and a large, flat primer punch to seat large primers.
Figure 6
Should you need to seat small primers, substitute the small
flat primer punch and sleeve packed separately using the
enclosed Hex wrench.
To install, remove the quick release pin from the priming
arm lug. Position the priming arm as shown in Figure 6. Reinsert the quick release pin.
To use the priming arm, place an unprimed cartridge case in
the shell holder and a primer (anvil up) into the sleeve of the
priming punch. Raise the ram to the top of its stroke and push
the priming arm toward the press. The priming arm will enter
the slot in the front of the ram and, as the ram is lowered, will
force the primer into the primer pocket of the case. This operation may be done when the cartridge case is being withdrawn from the decapping and resizing
die, but may be done later if you wish to clean or trim your cases before repriming.
Changing a Sleeve or Punch
To change another sleeve size or primer punch, use the hex wrench provided to loosen the
locking screw on the front of the priming arm, being careful not to lose the spring under the
priming sleeve. Install the new sleeve and primer punch and retighten the screw.
Installing the Primer Catcher
The plastic primer catcher is positioned cupside up, directly under the primer arm lug. Press
it firmly against the reloading press. Secure the primer catcher to the press by fitting the plastic retaining bar into the slots provided atop the sidewalls. It will catch and hold spent primers
that are decapped during the resizing operation.
Installation and Use of the Primer Feed for “T” Mag Presses (Optional)
Your automatic primer feed can be equipped with both large and small primer tubes. Small
rifle and pistol primers fit the small tube while large rifle and pistol primers fit the large tube.
The careful use of these tubes will speed the priming operation but remember to use extreme
care when handling primers.
The first step in installation is to place the primer feed body between the lugs of either location in the turret of the press as shown in Figure 7. Fasten in place using the furnished set
screws.
The primer feed body must be adjusted up or down until the drop tube is directly over the
priming punch sleeve when the priming arm is in the back position (see Figure 7). When this
adjustment is correct, the priming arm will pick up a single primer and, when pressed into the
ram, carry it into priming position. The remainder of the primers will be kept in the primer
tube by the cutoff pin.
When using the auto-primer feed with the T-Mag press the priming arm must be disengaged from the primer feed body to turn the turret past the priming station. To return to the
priming station, the primer arm must be pressed forward, toward the ram, to clear the primer
feed housing as it is rotated into position.
Filling the Primer Tube
To fill the primer tube, first insert one of the two supplied cotter pins through the hole in
the side of the primer tube. Spread the ends of the cotter pin slightly to keep it from falling
out. Next, place your primers anvil-side down in a small flatbottomed tray or dish.
Figure 7
T-Mag II (continued)
Force the slotted end of the tube down over each primer. The cotter pin will prevent the
primers from dropping from the open end of the tube when you turn it over.
Fill the tube completely, press the bushing (“0 ring”) end firmly into the primer feed body
and remove the cotter pin. One of the red plastic sleeves supplied should be slipped over the
open end of the primer tube to prevent injury should your face or arm strike to top of the
primer tube.
Lubrication and Care of Your Press
Before using your press, apply a light film of powdered graphite to the bearing surfaces of
all moving parts. Pay particular attention to the sides of the ram. Thin oil may also be used for
this purpose but graphite is more desirable. If your press is to be used in a damp area, it is recommended that you also protect unpainted surfaces with a thin film of oil.
Turret Support
The screw at the rear of the press serves as a support to the Turret when maximum pressure
is applied. Rotate the Turret and verify for clearance between the Turret Support screw and
the Turret. The screw should be adjusted so that it is slightly (about 1/64") below the bottom
edge of the Turret but not touching the Turret itself. Adjustment can be made by loosening
the locknut and turning the screw until the proper gap is achieved. Tighten the locknut. Rotate
the Turret and check for clearance. If the user feels further adjustment is required, the screw
can be moved in 1/8 turn increments until a satisfactory gap is accomplished.
A handy multi-purpose press/die accessory wrench is provided for making this adjustment.

CAUTION
Use extreme care when handling primers. Never mishandle any primer feed that malfunctions. Do not do anything that could cause a primer to explode when cleaning a
jam. Keep your work area clean, occasionally wiping dust with a damp rag.

INSTRUCTIONS FOR INDEXING AND REMOVING
THE TURRET OF YOUR T-MAG 11 PRESS
Your T-Mag II Press is supplied with a turret handle (item #2) which can be used for indexing or removing the turret from the reloading press. For easy indexing. insert the turret handle
into one of the two holes in the turret (item #3) and turn as desired. To change or remove the
turret, secure the press to a table or other fixed surface. Insert the turret handle through the
cross hole in the turret shoulder bolt (item #1). Using the handle as a wrench, loosen the bolt
in a counterclockwise direction and remove it from the turret. Lift the turret straight off the
press frame. When dies are installed in the turret it is necessary to rotate the turret slightly so
that the turret handle can be positioned between two dies. The turret shoulder bolt can then be
removed by turning both the bolt and turret. To reattach the turret, simply reverse the foregoing steps.
