Sky is falling hand waving FUD is not becoming of this site. No high speed impact, no bang is not entirely accurate in all contexts but it's the truth in this context. Your post is literally spreading FUD. It's not just the crush, the crush has to be of sufficient speed to generate a great deal of friction within the priming compound.You are applying pressure to the anvil. That is exactly how a primer goes off although the force is normally applied from the primer face to the anvil crushing the compound in between
I have never heard of one going off but I believe the only way for pressure to escape would be for the primer to blow out. I don’t think I would want to find out.
My recommendation would be to shoot them as is and keep all your body parts. What is an eye or finger worth?
It is surprising how much energy primers have. This is a test I conducted on a Federal 205M. The barrel length was 22”. Nothing but the primer in an empty case. Be careful everyone.

So why don’t you two experts contact any of the primer manufacturers and ask them if it is safe to press out live primers? Then post their response on this site. I’ll be waiting and waiting and…wrong...a primer is an IMPACT EXPLOSIVE.....no IMPACT no explosion. PUSH them out smoothly, and they are typically reuseable. just inspect and re use..i have done bunches of them this way......
I believe it is safe and I also use a Lee Universal Decapping Die. Go slow and easy works for me, this is so not to damage the primer so you can reuse it.I want t unload some factory.44 mag rounds that have accuracy problems. Is it safe to us the press to remove the live primers?
There's your KEY WORD right there. I PUSH and never TAP!!inserted the rod and gave a slight TAP as to remove the primer.
Have not done as many as other guys. I wear safety glasses and put a heavy cloth over the press. Never had one go off. The hole that the primers drop thru in the press is filled with black particles. If a primer went off these particles will be blown out with some force. Protect your eyes you are issued one set.I want t unload some factory.44 mag rounds that have accuracy problems.

Well, I disagree a little bit with this statement. I reuse these primer in Fouler rounds when shooting strings, I will have them separate in a different container.Yep. Primers will probably not be very reliable afterward so soak in something and discard when done. Just treat them like otherwise live primers once deprimed from the case.
This is where I am at on this. It takes almost no pressure to pop out live primers. I don't have a dedicated decapping die but I usually have some die bigger that will not touch the case when I push the primer out. I reuse those primers for foulers or plinking loads. I've never had one fail to go off.Well, I disagree a little bit with this statement. I reuse these primer in Fouler rounds when shooting strings, I will have them separate in a different container.
The last instance I had where I had to deprime was "something" happened to the case mouth that it was flared and had to be turned, a 21st Century lathe works best without primers in so I deprime them.I add also, why de-prime them? Just flare the case mouth some, and reload the cases with the new powder and bullet.
Because he was annealing the cases. I use the sound test for my 44 mag cases. Most will have a dull sound when you stir them around in the case. Some will have a clearer sound like a tiny bell. Those ones need to be annealed or they may split/crack in your revolver. Ask me how I know....I add also, why de-prime them?

Oh my gosh no! Totally unsafe! Don’t ever do it. Where’s common sense at? Lord love a duck!I want t unload some factory.44 mag rounds that have accuracy problems. Is it safe to us the press to remove the live primers?
