bluesj Posted February 27, 2016 Report Share Posted February 27, 2016 I've been given a load of primed cases but I don't know what primers are in them or if they have been full length or just neck sized. Is there a safe way to de prim them or should I just get rid of the? I've used WD40 in shotgun cases that have miss fired but never remove the primer after so not sure if it completely kills the primer.

chris1961 Posted February 27, 2016 Report Share Posted February 27, 2016 I either use my mec reloader or a 6inch nail and a block of wood with a hole cut in it works a treat never had one go off yet Quote Link to comment Share on other sites More sharing options...
SPARKIE Posted February 27, 2016 Report Share Posted February 27, 2016 (edited) fire the primers of if there not loaded the just deprime as normal if your wanting to use the case..... Edited February 27, 2016 by SPARKIE Quote Link to comment Share on other sites More sharing options...
saddler Posted February 27, 2016 Report Share Posted February 27, 2016 Most SHOTGUN primers I've seen were totally sealed against moisture (or whatever) WD40 squirted into the case doesn't work (ask me how I know)!! Rifle brass. Some dies you can remove the decapping pin part of the rod. Lee dies, not removable. I've removed hundreds of live primers with no problems...just go SLOWLY & wear good eye protection in case one pops. Quote Link to comment Share on other sites More sharing options...

fortune Posted February 28, 2016 Report Share Posted February 28, 2016 If they are rifle cartridges I'd just use the primers that are in there now. It won't make much if any difference unless you are loading a really hot load right up on the max. Quote Link to comment Share on other sites More sharing options...

The OP possibly wants to full length size them Quote Link to comment Share on other sites More sharing options...
fortune Posted February 28, 2016 Report Share Posted February 28, 2016 If you have been given the cases ask the person who gave them to you if they are new and unfired. You will have to full length resize the cases so that they will chamber in your gun if they have been fired. Why do you want to remove live primers? If the cases have been primed just load them and fire them. It won't make much difference what they are unless you are loading a very very hot top line load. They will either be a STD primer or a magnum primer and some powders need a mag primer to burn correctly anyway. If the person who gave them to you doesnt know if they are unfired then proceed slowly and carefully chamber one of the cases to see if it will chamber or not. If the case binds up don't ram it home but gently use a rod to remove it and then full lenght resize it. Quote Link to comment Share on other sites More sharing options...
ninja_fox Posted February 28, 2016 Report Share Posted February 28, 2016 Why not just put the empty primed cases in your rifle & fire off the primers? Then you can do what you need with them... I would not want to be trying to de-prime live cases. Quote Link to comment Share on other sites More sharing options...
kent Posted February 28, 2016 Report Share Posted February 28, 2016 It's very hard to kill primers with anything if you try if you don't try it's quite easy Seriously years ago I took various primers and applied various things to them, the next day they all fired Just fire them off and decap it's safer Quote Link to comment Share on other sites More sharing options...
Dougy Posted February 28, 2016 Report Share Posted February 28, 2016 Resize all by removing the de-capping pin. Why waste the primers, Quote Link to comment Share on other sites More sharing options...
Vince Green Posted March 3, 2016 Report Share Posted March 3, 2016 (edited) From reading the post I think the concern is if the cases have only been neck sized. The OP possibly wants to full length size them Try putting them in your rifle and closing the bolt. That will answer the first part of the question. Sometimes even a neck sized case will chamber in another rifle but I understand they may be full length resized the OP wasn't sure Edited March 3, 2016 by Vince Green Quote Link to comment Share on other sites More sharing options...
