    I have about 100 short mag cases sized, trimmed, chamfered and primed. I load them when I need them. I just realized I have had a bad batch of primers. About one in three is a dud.

    How can I remove these primers without re-sizing the brass? I would like to pop them out and just put new ones in and be ready to load.

    Yup. The Lee unit works well.

    Shoot something into the case to kill the primer then adjust your decapping rod down so it pops the primer out before the case sizing starts. I do this all the time to pop out old primers so I can get case measurements prior to sizing.

    "Shoot something into the case to kill the primer ..."

    I don't know what you shoot your primers with but they're a lot more difficult to kill than most people think. I suspect if you chamber and fire some of your 'ded' primers you'll get a surprise. Hardly matters, it's perfectly safe to decap live primers anyway you want to.

    I don't spray anything in the case...I just very very easily and carefully pop them out with an RCBS universal decapping and depriming die. Then I put them in an old powder container that I use for an old powder dump, then when it gets full we take it out to my buddy's land, then mix in some tanerite and shoot it from a long ways away and watch it go BOOM! Safe and fun disposal. :D

    I used to dump powder in the terlet (Futurama joke)...But the tanerite method is so much more fun.

    I have to admit, I've only done 5 but only after a friend showed me using normal de-priming process with regular dies; apparently he's been doing it for many years.

    There is no way I'm depriming a live primer, I soak them with penetrating oil and they won't go of in a rifle so GTG. Didn't we have a thread a few years ago on here that a guy had to have a primer anvil removed from his fingers, I know one other incident of a primer lighting during reloading.
    Reloading has the potential to be dangerous, why push your luck in any way shape or form!!

    I've deprimed a few live primers over the years. I wear ear muffs and eye protection. Then I go slow motion. Never had a live primer go off during depriming. That doesn't make me an expert on the subject. I haven't removed 100s of live primers. Just saying I haven't had one ignite.

    I like the Lee Decapping Die referenced earlier. It's very stout and only deprimes. Doesn't resize the cases at all. Deprimes all the differing cartridges I reload for. It will even remove military crimped 5.56 fired primers. Great for depriming field pick up 5.56 casings.

    I load the cartridge with the live primer and fire it out the back door. It is not loud, but you can see a little smoke/spark come out of the barrel. I then decap it. I have done it both ways (decap live) with no issues.

    From what I have read ( not a primer or explosive expert by any means) that explosive in primers has to have high impact before exploding. Crushing does not do it. I have actually crushed a few priming the cartridge before, sometimes I am an idiot. BUT I have heard/read that primer dust is a different story, it CAN explode. So there is risk from decapping live primers to accumulate primer dust after decapping a lot of primers and it IS possible to set that off. I believe that is why Hornady no longer sells the auto priming tube for their press. There were reports of primer dust accumulating and exploding.

    Potentially dud primers are good for practicing sight picture/ trigger squeeze/ follow thru. .
    Or u can just deprime the cases. I've done it lots. . Say at least a couple hundred over the past 30+ years of roloading. .
    Yup. Hundreds! Never had one go off yet. Long skiff rides home. 50+ miles in rough weather. In a the winter. Action Packers are great for keeping stuff dry from rain and snow. But they are not water pruf when submersed. I had about 8 bricks of LRM primers get soaked 1 time. I dried them out on top of my Blaze Queen wood stove.
    It's amazing how cruddy a primer can look with dried salt on it and it still works great. It's also amazing how a primer can look pristine and be a dud. ????? Go figure.
