User Instructions for the Forster Products Co-Ax
®
Reloading Press Issue 4
1.0 GENERAL INFORMATION
The Co-Ax® Reloading Press is designed for two main
purposes:
1. Rifle and pistol case resizing and bullet seating.
2. Rifle and pistol primer seating.
The Co-Ax Press accepts any 7/8" X 14 rifle or pistol reloading
die. For proper press operation, you must use our aluminum
Cross Bolt Die Lock Rings (two are provided in the Important
Parts Packet – see Figure 2) on either your own dies or on our
Forster Products Reloading Dies. Using our Cross Bolt Die
Lock Rings is important for two reasons:
• They keep the Co-Ax Press T-Slot free from wear that may
be caused by other harder steel lock rings.
• They are the proper thickness to allow the dies to “float” in
the T-Slot for optimal reloading.
CAUTION
PRODUCT DAMAGE
• Do not drop or expose the Co-Ax Press to sudden
stresses.
Failure to comply with these instructions may result in
product damage.

3.0 SAFETY INFORMATION
WARNING
PERSONAL INJURY
• Avoid possible pinch points.
Failure to comply with these instructions could result
in death or serious injury.
Always wear safety glasses.
4.0 MOUNT THE CO-AX PRESS TO A WORK SURFACE
The Co-Ax Press may be directly mounted to a work bench, or
to a board for later use on the range or in the field. Due to the
extreme mechanical advantage engineered in the Co-Ax
Press, only two “C” clamps are needed to fasten the board-
mounted Co-Ax Press to a working surface.
1. See Figure 11 on the back page for a scale drilling
template.
2. Drill four ¼” holes. Mount the Co-Ax Press using ¼” lag
bolts.
5.0 SETUP AND ASSEMBLY
5.1 Install the Handle
1. Insert the Handle into the B3 Yoke Handle Casting (-055).

tighten the Handle Set Screw (¼-28) (-014).
Note: A short handle with a ball end is available separately for
use when less leverage is needed. See Section 9.0.
5.2 Install the Primer Catcher (See Figure 1.)
1. From below, insert the threaded part of the Primer Drop
Tube (-053) through the hole in the Primer Catcher Cap
(-050).
2. Screw the Primer Catcher Cap to the Primer Catcher Cup
(-051).

5.3 Adjust the Jaw Opening Screw (-044) (See Figure 2.)
The Jaw Opening Screw controls the amount the lower
Shellholder Jaws open to accept cases when the Handle is
raised to its highest position. Adjust the Jaw Opening Screw’s
height so that the Shellholder Jaws completely open when the
handle is in the full up position against overhead stops, but not
too far that it could damage the Shellholder Housing (-037).
