DANGER

  • Ammunition reloading can be dangerous if done im properly and can result in serious injury or death.

  • Reloading rifle ammunition requires extra care due to extremely high pressures. Make sure your cases are in good
    condition. Inspect them before each reloading for damage and wear. Cases must be trimmed. An excessively long case will pinch the bullet in the end of the rifle chamber and cause dangerously high pressure that could damage your gun and cause personal injury.

  • Use only Remington™ or CCI™ primers. If you use other brands, you must have the Explosion Shield installed. Other brands like Federal™, can explode with sufficient force to seriously injure the user or persons nearby. Never place more than 100 primers in the tray.

CAUTION

  • Reloading should not be attempted by persons not willing and able to read and fol low instructions exactly. Do not permit distractions while loading. This is a complex machine that needs your fullest attention.
  • Children should not be permitted to reload ammunition without strict parental supervision.
  • Always wear safety glasses and hearing protection when reloading and shooting.
  • Ammunition loaded with these tools and data should only be used in modern guns in good condition. We do not accept responsibility for ammunition loaded with these tools or data as we have no control over the manufacture and storage of components or the loading procedure and techniques. Primers and gun powder, like gasoline and  matches, can be dangerous if improperly handled or misused.
  • Verify proper powder and charge for bullet weight selected.
  • Be extremely careful to avoid a double charge. If in doubt, empty the case and recycle it.

TOOLS REQUIRED:

Safety glasses & ear protection Pencil
Qty. 2,7/16 wrenches for cylinder and plate nuts
11/16 wrench for feed rod bracket nut

2 Phillips screwdriver for case retainer and bin and bracket

Flat blade screwdriver
Any automotive grease
STP® motor oil treatment for lubricating ram

SMOOTH OPERATING TIPS

  • After every use, oil the ram with STP® motor oil or equivalent. DO NOT USE WD-40 or dry lubricants.
  • After 3000 rounds, or if press has sat idle it should be re-lubricated. See Lubricate Press section on page 8.
  • Don’t let the primer level fall below the tray level. Running out of primers will cause a mess inside carrier.
  • Always move the lever smoothly in complete strokes. An interrupted stroke can cause a jam or double charge.
  • Do not force it or you will break something. If it does not feel right, stop and check out the problem.
  • Keep your press clean. Clean the shell plate shell slots, dirt or gunpowder will keep the case from fully entering the shell plate.
  • Frequently check primers to make sure they are seated properly. The primer seating punch inside the carrier should be clean. Dirt may deface the primer.
  • After 3000 rounds, empty the spent primers. To empty, slide the cover back at the bottom of the ram. Place a container under the ram to catch spent primers. Be sure to close the cover, or it will get bent the next time the ram is raised.

1 Mount your press
The most convenient way to mount your press is with our Lee Bench Plate System

90251. This system includes press mounting hardware and allows for quick

press removal without unbolting from bench. This will require (qty. 4 ) ¼” bolts for mounting the Bench Plate System. If bench is 3/4” or thinner, use at least ¼” through bolts with nuts and washers. If bench is 3/4” or thicker, 5/16” lag bolts work nicely.
Or, if you mount directly to bench, purchase (3) ¼” bolts and nuts and prepare your workbench for use with this press using the drill template available: leeprecision.com/files/instruct/TMPLM.pdf

Install Explosion Shield
to your press. Unscrew the two Phillips screws in the red frame and attach Explosion Shield. The deflector should be between you and the primer tray when the carrier is all the way up.

Use only Remington™ or CCI™ primers. If you use other brands, you must have the Explosion Shield installed. Other brands like Federal™, can explode with sufficient force to seriously injure the user or persons nearby.

Install Case Slider Block
Cases are slid close to the shell plate on the down stroke of the ram and pushed into the shell plate as the ram starts upward. This unique action is achieved with crank slider.LEE PRECISION LM3231 Load Master 5 Station
Reloading Press - brand of lubricantThe feed bracket can easily adjusted in or out as required to fully insert the case. Once set, usually no further adjustment is needed unless you change from a very large case to a small case.
See chart on page 10. Some cases require riser to be installed on top of case slider block.

Slide the RISER block on top of CASE SLIDER BLOCK until the front and back are flush. Tighten Phillips screw on riser block.
Slide the case slider block on to the carrier tongue. Take the case feed rod, which has the crank slider already installed on it from the factory, and insert the crank wire of the crank slider into the rear hole. Insert the round end of the square case feed rod into the feed rod bracket. Case feed is square, align a flat parallel to the carrier tongue. Do not place any lubricant on the case feed rod.

1Cycle the press to be sure of free motion of the case slider. At the upper most ram travel, place a case in front of the case slider, and cycle the lever.
Tighten top screw of the crank slider. If you manually slide the case slide in and out, you will feel how much tension is on the bottom screw. Tighten the bottom screw to increase the push on the case.LEE PRECISION LM3231 Load
Master 5 Station Reloading Press - top screw DRY RUN (NO PRIMERS, POWDER OR BULLETS)
Cycle the lever up and down a few times to get the feel of your machine.
We suggest a slow to moderate lever speed. As the ram starts up, the caseslider should move in and flipper will be turned slightly to the left at the mid-stroke and back again at the very top of the stroke. See [FIG. 1].
When you operate the lever, you must make complete strokes, stop to stop. Failure to complete the up stroke can cause index flipper to put in a “half- cocked” position at mid-stroke and cause press to bind. Continued pressure may damage the ejector pawl. If you short stroke the press, pay attention to the indexer as it pulls out of the carrier at the mid-stroke position. If you feel it bind — STOP — and pull the indexer out manually to the edge of the frame before completing the down stroke.
About halfway down, the indexer will be pulled toward you by a raised rib and moved to the right by the sloping projection on the frame. See [FIG. 2 AND FIG. 3].
Near the bottom of the stroke, the lever will push against the indexer and smoothly rotate the shell plate.LEE PRECISION LM3231 Load Master 5 Station

One Last Step! Very Important! Set case retainers.
Place a case in front of the case slider and raise lever to insertcase into shell plate. The case retainers are designed to swing out so you can easily remove a case from any position. They must be set so that they hold the case fully into the shell plate.
Place a single case in the shell plate and forcefully push the caseretainers with a flat bladed screwdriver against the case rim at all four stations. NO NEED TO LOOSEN RETAINER SCREWS.
The case retainers precisely position the case so that it will be centered to enter the dies and most important to center over the new primer in the second station.

The Lee Factory Crimp™ die does not seat the bullet — it should be seated with the bullet seating die.
Fill the primer feed tray. View help video here for loading primers into tray: leeprecision.com/load-master-help-videos.html
Don’t let the primer level fall below the tray level. Running out of primers will cause a mess inside your shell plate carrier. Once the last primer has exited the folding tray, replenish the primer supply, else you will load cases without primers.
DANGER:
Use only CCI™ or Remington™ brand primers. Other brands, espec ially Federal™, can explode with sufficient force to seriously injure the user or persons nearby.
ALL PRIMERS ARE DANGEROUS and it should be anticipated that the primers in the tray could explode through accident, misuse or spontaneously. Should an explosion
occur, our tests have demonstrated that safety glasses will normally prevent serious injury to the user if CCI™ or Remington™ primers are used, because the explosion is minimal. Other primers, however, can explode with sufficient force to seriously injure the user, or persons nearby. We do not take any position with respect to the quality of performance of primers available on the market. However, ONLY those primers manufactured by CCI™ or Remington™ are recommended for use in the Load-Masterand when loading those primers—safety glasses and hearing protection must be used. If you use other brands, you must have the Explosion Shield installed (see step # 2). Other brands like Federal™, can explode with sufficient force to seriously injure the user or persons nearby.

Lift tray so output spout touches table, shake tray side to side to upright all the primers. Allow cover to naturally fold up, notice how the primers glide across hinge upright themselves and work their way towards the outlet. Fold cover over, slide the flow control to LOCK position, feel for the detent. Grasp the top and bottom of the flow control valve using your thumb and index finger above and below tray. NOTE: make sure it is in the LOCK detent position, else primers may spill.

8Slide the tray into the trough. Slide the flow control to the ON position. Tap the side of the tray several times to fill the trough.
Before making an adjustment, be sure none of the dies are seated too deeply in the press.
LEE PRECISION LM3231 Load Master 5 Station Reloading Press - fig
9 Set Primer Seating Depth
The ¼-20 bolt that bears against the primer rocker arm may require some fine adjusting to seat primers to your liking. Make very small adjustments and test after each. There is sufficient spring in the linkage to accommodate slight differences in cases. First, make sure that the press is stopping on the stop built into the handle, not on one of the dies. Next, place a fired case with the spent primer still in it in station # 2.
Loosen the lock nut with 7/16” wrench on the primer seating depth adjuster, and turn the adjuster up until you run out of threads. Now raise the ram to the top of its stroke with the fired case in station #2. Holding the ram up with one hand, turn the primer seating depth adjuster down until you feel resistance. This will be when the primer seating pin contacts the spent primer in the case previously inserted into station #2.
Lower the ram, and turn the primer seating depth adjuster down ⅙ – ⅓ more (one to two flats on the bolt head), and tighten the lock nut.LEE PRECISION
LM3231 Load Master 5 Station Reloading Press - fig 10 Install Feed Plate
Before attaching the 4 tube case feeder, place an empty case in front of the case slider. Process 50 to 100 cases until you have the feel of the entire reloading sequence. Be sure to measure your completed ammunition to verify it is the correct overall length and it will chamber in your firearm.
SEE IMAGES on page 7 TO SET UP YOUR PLATE, cartridge reference chart available on page 10. Raise the shell plate carrier to the top of the stroke. Insert case in front of slider. Place a coin on top of the case mouth. Slide the feed plate assembly into the carrier hole, and adjust the top nut so that the bottom of the feed plate assembly rests on top of the coin. Tighten the bottom nut so that the feed plate assembly just clears the front face of the frame using a 7/16” wrench. Refer to the back page of these instructions to insure the proper slider and cylinder and plate are used for the cartridge you are reloading. Slip the four tubes into the case feeder and fill them with cases. Fill tubes in seconds with optional case collator # 90667. >> CONTINUED ON TOP OF PAGE

  • Changing cartridges is quick and easy with the removable turret. It is precisely aligned with the knurled lock screw on the left of the press. Loosen the screw so the turret can be rotated about 3/8” and lifted out. When replacing, make certain the lock screw engages the groove in the turret.
  • Fastest way to change dies is to have them installed in their own turret. It then becomes very fast and easy to replace the entire turret.
  • Consult the back page of this instruction sheet for guidance on what parts are required for changeover.

CHANGING THE PRIMING PIN AND PRIMER FEEDER

CHANGING CARTRIDGE SETUP

To convert the Load-Master from a one cartridge to another, you will need the proper shell plate, primer feed, and appropriate Lee 3-die set. The chart below shows proper configuration with catalog numbers. Identify your current press configuration by cartridge. The chart will list which components shipped with your press (primer feed, shell plate). Then check the cartridge you wish to load, to see which components match with your current press configuration. Order any components that do not match (primer feed, shell plate, dies or powder measure).
