  • A step by step demonstration of the Lee Loader tool set for reloading the 3" .410 shotgun shell. The steps in reloading a shell are: de-priming; priming; charging with powder, seating a wad, filling with shot, and finally crimping. The tool may be used to form either a roll crimp or fold crimp.

    Good clip. Brought back good memories. I bought mine form Dixie Gun works back in the late 1970s & used them for years, before I finely got a Mec reloaders. I have one in .410, 28, & 10 ga. Picked up the 10ga one @ a gun show back in the 80s sometime. I have not used them for years now, but they would still work just as intended today, as they did years ago.

    With the cost of 410 shells and in areas that are very remote this would be a life saver. I have the 410 Survival Reloader by the X Ring and it is about 88.00 and works well. I also have Mec 600 but had to start somewhere . Will always keep the hand tool. Not much in the way of components to loading a 410 when they cost around a buck each for factory.

    • @314299
      @314299  Před 4 lety +3

      I don't see any part number, however the dimensions are: 0.50" diameter, 0.20" thick with a 0.25" hole in the center. Hopefully that helps.

  • @aarondavenport3143
    @aarondavenport3143 Před 3 lety +1

    It might be easier to crimp by using the other side of the dye body (i.e. side used to remove primer) and then using the handle end to push in the crimp.

    • @314299
      @314299  Před 3 lety +3

      That would not work as it's the geometry of the inside of the die that curls the crimp in, with the die backwards it would not work.

  • @aarondavenport3143
    @aarondavenport3143 Před rokem

    Might the spacer also allow for more force to be used in crimping without worrying about setting the round off (perhaps using a few gentle taps with the mallet etc...) in that it reduces any concentration of pressure directly onto the primer?

    • @314299
      @314299  Před rokem

      As long as you are applying crimping force by pushing and the shell is on a smooth surface there is almost zero possibility of the primer going off. Primers are set off by percussion, so I can not recommend any crimping that involves hitting the loaded shell with a hammer or mallet.

  • @ohiorusty4982
    @ohiorusty4982 Před 4 lety

    I just bought one of those .410 lee loaders for 3 inch shells. That kit is missing the spacer with the hole in the middle you are using to force the shell body higher in the tool. Can you give some dimensions of the spader so i can make one ?? Width across and thickness ?? I can drill the hole after the spacer is made. Thanks ... Rusty in Ohio

    • @314299
      @314299  Před 4 lety +1

    Can you tell on the 410 Lee Loader, is the body/die stamped with that information; or what does it say? I have the kit, I want to confirm that I have the original components. Someone thinks the die might be a 28 gauge....Is that possible?

    • @314299
      @314299  Před 3 lety +2

      There are no gauge markings on the loaders I examined, all the gauge info is on the load data/instruction sheet. It should be pretty easy to see if what is present in the kit is correct for the gauge marked. If you have a fired shell and a wad you can compare those to the tools present to see if they appear correct.

    • @314299
      @314299  Před 4 lety +1

      Yes, I did load some 12 gauge shells with the "000" buckshot that I cast in the Lee mold. I did not have much success finding a load that functioned well, the issue was that the loaded shells were "lumpy" and were hard to chamber. The "000" pellets are just so large that they dont stack well, at least not in any combo that I tried.

  • @jjh9355
    @jjh9355 Před 3 lety

    Is there a reason why you used hand pressure to make the roll crimp and not the mallet? I assume you want a good starting crimp, but once it is well started, why not use the mallet?

    • @314299
      @314299  Před 3 lety +2

      Pounding on a fully loaded shell is a bad idea as primers are set off by impact/shock, so there is the possibility of it going off. Pushing on the shell does not involve the same risk of a primer and therefor the shell going off.

Rem hulls are shorter, that's why the washer in sand colored envelope. These look like federal hulls. Old federal had different primer pocket shape than newer 209a type. Older more win rem cci shape, newer more bell shape at rim. Mec starter crimp may help a bit for fold. Crimps nice enough. Lee of this type waaay overpriced on fleabay. Other alternatives available, check on CZcams. Used mec 600 jr is super, as is pacific 155. As you can see it's slow but they do have their purpose. Thanks 4 all the videos.

      Wad pressure is used to compress the wadding slightly to get the total package of powder, wad and shot in the shell without air. A shotgun shell has to be loaded to fill the entire shell without void or space between the powder, wad and shot. Otherwise poor ignition and strange ballistics can result,

    How do I do a slug

    • @314299
      @314299  Před 2 lety

      The process is essentially the same except you insert a slug instead of pouring in the shot. As for .410 slugs where are you going to get those for reloading? I've not seen any for sale.

      410 Lee Loaders do pop up for sale on eBay occasionally but they do generally command high prices. Occasionally one will show up at a gun show or flea market for a decent price.

      The metal can is indeed older but the contents are not, I get bulk packaged 296 powder and put it into the metal cans for storage, so the powder is only a couple years old.

      I tried a couple of on-line translation tools on your comment but the results they gave me were odd, here's the result one gave:
      "I can't believe Americans don't have a twist. (I don't believe they didn't have a twist, table or handheld. We never had a .410 before, and soon there was a cartridge-firing device... Pick one and take it at your own discretion. I don't need to bother with that hammer set."
      I'm going to assume your comment was something like "I cant believe you dont have a reloading press, there are many available, pick one and no need to bother with the hammer set." If that was close to the intended comment, here is my answer.
      .410 reloading presses are indeed available, in fact I have two, both are MEC single stage units, one set to load 2-1/2 and one for 3" shells. However the video is not about those, it about using the now discontinued Lee hand tool set. Apparently it is topic of interest to some people as over sixty-six thousand folks have watched the video at this point. Have a nice day.

    That looks like a old used fired hull ? Try using that tool on a new hull good luck it just does not work at all !

    • @314299
      @314299  Před rokem

      Are you trying to do a roll crimp or a fold crimp on the new hulls? Roll crimping should go well on new hulls, however if you are trying to fold new crimps you will need to add a six point crimp starter. A crimp starter was not included with the set used in the video but may have been included with later production "deluxe" sets. If you cannot locate and original Lee six point .410 crimp starter you should be able to find a crimp starter for a MEC machine, they are cheap and work the same. What brand of hull are you trying to reload?

    Dont crush your wad down so forcefully, thats not necessary. You will end up not need so much of a roll crimp.

    • @314299
      @314299  Před 8 měsíci

      Most lead shot wads for 10/12/16/20/28 gauge have a cushion section but standard 410 wads do not, therefore you can not "crush" these 410 wads as they don't have a cushion section to crush. Pushing the wad down forcefully is done so as to compact the powder for better ignition. The powders used in 410 shell are very slow burning compared to other shotgun powders and work best if firmly confined by a solid crimp, and a deep roll crimp also insures better ignition of these slow burning powders.
