Ensure a clean, stable, and well-lit workspace for efficient reloading. Clear clutter and position the MEC 600 Jr. Mark V on a sturdy bench or table. Proper ventilation is essential to avoid inhaling gunpowder or primer fumes. Keep all necessary tools and components, such as shell holders, powder, and wads, within easy reach. Refer to the manual for specific workspace layout recommendations to optimize your reloading process safely and effectively.

Mounting and Calibration

Mount the MEC 600 Jr. Mark V securely on a sturdy bench using the provided hardware to ensure stability. Align the machine according to the manufacturer’s instructions for proper operation. Calibrate the reconditioning station and wad feed system by following the manual’s step-by-step guide. Adjust the shell holder and powder charge bar to match your specific load requirements. Proper calibration is critical for consistent reloads and safety. Refer to the manual for precise alignment and adjustment procedures to ensure optimal performance.

Step-by-Step Loading Procedure

Start by resizing the shell, then recondition and prime. Add the powder charge, insert the wad, and place the shot. Finally, crimp the shell to complete the reload.

Resizing and Reconditioning

Resizing and reconditioning are the first steps in the reloading process. Place the shell on the resizing tube, ensuring it’s aligned properly. Lower the lever to resize the brass base, restoring it to factory specifications. Next, the cam-actuated reconditioning station removes old primer residue and prepares the shell for a new primer. This step ensures a clean, precise fit in the chamber, guaranteeing consistent reloading results. Always follow the manual for proper technique to avoid damage to the shell or the machine.

Priming and Powder Charging

After resizing, place the shell into the priming station and insert the appropriate primer. Lower the lever to seat the primer firmly. Next, move the shell to the powder charging station. Use the charge bar to dispense the correct powder amount, ensuring it aligns with your load specifications. Always refer to your manual or a reloading guide for precise powder charges. Handle primers and powder with care, as they are sensitive components. Proper priming and charging are critical for consistent and safe reloads.

Wad and Shot Placement

After priming and powder charging, insert the wad into the shell using the Adjusta-Guide wad feed device, ensuring proper alignment. Next, add the correct amount of shot, either lead or steel, depending on your load specifications. Use the shot bar to measure accurately and ensure the shot settles evenly. This step is crucial for achieving consistent patterns and balanced cartridges. Always follow the manual and load guidelines for precise wad and shot placement to ensure safety and optimal performance.

Final Assembly and Crimping

Once the wad and shot are correctly placed, carefully lower the shell into the crimping station. Use the crimp die to fold the shell mouth evenly, ensuring a tight seal. Apply steady pressure to complete the crimp, following the manual’s guidance for the correct depth. Proper crimping prevents spillage and ensures consistent patterns. Double-check the crimp for evenness and tightness before considering the cartridge complete. This step is critical for reliable performance and safety in the field.

Maintenance and Troubleshooting

• Regularly clean and lubricate moving parts to ensure smooth operation.
• Refer to the manual for troubleshooting common issues like misfeeds or incomplete crimps.

Cleaning and Lubrication

• Clean the reloader’s frame and components regularly with a soft brush to remove residue and ensure optimal performance.
• Lubricate moving parts, such as hinges and wear points, to maintain smooth operation and prevent corrosion.
