Speed-De-Capper caliber change instructions

The Speed-De-Capper (SDC) patent # US 10,712,139 b2 is designed to remove spent primers from .380 through .45 ACP auto pistol cases only. It is adjustable and may work for other calibers that are no longer than a .45 ACP case. The SDC should be bolted to a sturdy work bench before any use.
Only two adjustments and four steps are required to change caliber size.

  1. Remove the shell holder clip assembly and shims by removing the button head bolt from the rear of the unit. Shim storage is at the rear, under the wing nut
  2. Install the recommended shims (see below) for caliber to be deprimed. Take a spent primed or un-primed case of the caliber to be deprimed and place it in the clip assembly. Visually align it under the punch pin and carefully punch out the primer, leaving the punch pin all the way in the primer hole, handle at the 3:00 position. Reinstall the bolt in the rear.
    Test and trial units: 2 shims .45, 3 shims .40, 4 shims .380 and 9mm.
    NEW updated units: 0 shims .45, 1 shim .40, 2 shims .380 and 9mm.
    This aligns the center of the case under the punch pin. Raise the pin punch and watch the case as you lower the punch/stripper spring into the case. The case should not move and the pin should go through the primer hole easily.
  3. Now adjust the slide stop position. On the back you will find two wing nuts for this adjustment. Loosen both wing nuts about 1/4″ from the block they are against. With a case in the holder, rotate the handle to the 12:00 position. With your index finger push the slide from its end against the case in the holder, lightly. Now while holding the slide against the case, adjust both wing nuts against the block finger tight. Place a case in the slide channel and advance it to the case holder. It will pop in place and you will know this is correct when the punch pin will go in and out of the case exactly with no case movement. Tighten the wing nuts securely.
  4. Case feeding. A reducer tube is used for .380 and 9mm cases. Before attaching the case feeder, advance the slide forward. A small hole is drilled in the tube for easy lifting/removal with an Allen wrench, so install the tube with the hole at the top. Insert the reducer tube in the feeder hole. Lift it slightly so it does not contact the slide. Snug up the set screw (shim storage) to retain the tube Install the feeder. No tube is required for .40 and .45.

NOTE: the weight of the stacked cases keep the cases upright as they drop down, so watch the last few cases dropped from the tube as they may not feed correct at a high speed. (The case does not drop fast enough in front of the slide with out the weight.) Hint: Just keep the tubes filled more than 1/3 the way.
Always slowly run a few cases watching for any case movement as the punch enters into the case and primer hole. The next case should push the punched case through and it should drop clear. (There will be more drop clearance on the new versions.) Build speed slowly to about one case per second. This allows you to stop and clear any damaged, upside down or wrong caliber cases. Difficult crimped (military) primers will stop the unit and you may have to reverse half way and hit them hard. SORT these out by catching them as they drop out. Chamfer these cases before trying to reprime them!

-Be sure no debris drops down the feeder tubes with your cases. Any and all dirt, stones, etc. will end up in the slide if using the LEE case feeder. Using an old bath towel, tumble the the debris from cases before you load the feeder with them.
-If you encounter an issue, index the LEE feeder part way to stop the feed from the tubes. Clear the unit and be sure it rotates freely.
-LUBRICATION….Initially and every few hundred cases, put the handle at the 3:00 position, add a few drops of light oil in the top punch guide hole. Lightly grease the slide and slide channel. Any gun oil/grease should be fine. Delrin (plastic) slides require no lubrication.
