How to use Mec 600 JR Reloading Press

  • The first step is checking your manual for information about the correct type of powder type and amount to use, this depends on which particular shotgun one is using. Only use items that are specified for the load you’re using.
  • Gently remove the hex bolt and recharge bar on top of the main press using a standard Allen wrench. Add powder bushing on the charge bar then replace your press. Reinstall your bolts which hold together the charge bar then slide them into position.
  • Remove plugs from the synthetic containers above, then fill appropriate containers with necessary powder and the opposite chamber with shot. Also replace plugs at this stage if it’s required.
  • Carefully check the used shotgun shells for any signs of cracks, tears or other related damages. Throw away units that appear damaged. Thereafter, proceed by fixing your shell into the primary station found at the rear left side of your cartridge. Gently lower your handle so that the de-priming unit can replace what has already been spent.
  • Resize the brass section of your shell to a correct size then raise its handle to top position. Fix your primer into the cup on the 2nd station found right in front of the primary station. Proceed by moving the shell to third stage in front of the main press. Lower the machine handle till the charging tube fully fits inside the primary shell.
