Lyman® Ram Prime Die System ✔NEW ✔Low Price ✔U.S. Shipping ✔Authorized Dealer 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. 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 reloading. 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 adjustment 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. Press and shellholder not included.
