Lyman Ram Prime

Lyman Ram Prime Die
This die is designed for sensitive one-at-a-time primer seating on
top of a press. The Lyman Ram Prime Die works with all 7/8" x 14
threaded presses. It includes large and small primer punches.
Screw your Ram Prime Die into your press as shown in the illustra-
tion. Remove your shellholder from the ram and install the primer
punch pusher into the ram of your press. Make sure the Ram Prime
Die has the proper shellholder installed for the cases you are reload-
ing. The shellholder should be facing you.
Adjust your die either upwards or downwards with the following
suggested method. Insert a case with a fired primer fully into the
shellholder. Move the ram to the top of its stroke and adjust the die
until the primer cup just begins to engage the bottom of the case. Now,
slowly rotate the die until the primer punch engages flat to the base of
the case. Tighten the lock ring set screw.
Inset a primer into the primer cup. Make sure you use the proper
size priming cup. Make sure the primer is the proper size for your case
and the anvil of the primer is facing up in the primer cup. Make sure
your case is in position in the shellholder. Slowly bring the ram up and
insert the primer into the case. Make sure the primer is seated .002" –
.006" beyond the base of the case head. Some minor further adjust-
ment upwards or downwards on the die may be necessary until the
primer is seated satisfactorily. Due to the mechanical advantage of the
press, it is possible to overseat or crush primers during seating.
Insufficient or excessive primer depth seating can greatly reduce
primer sensitivity and could result in misfires. You must exercise care
until you learn the proper “feel” of your press. Remote priming is a
popular option with many reloaders.
Caution: Always use extreme care when handling primers. Never
stand or work directly over your press when performing the primer
seating operation. Never force primers into pocket. Always read and
understand the manufacturer’s cautions before handling or using
primers. Always wear safety glasses or goggles when seating primers
