Safe way to unprime cases

I frequently deprime by running them into my universal decaping die. Never had one pop, but it could happen. When doing this, you are pushing the anvil backward, so that it should not fire. I always wear safety glasses when doing this. The best way would be to pour water or oil in the case, then deprime.

Give the primed brass to the rifle buyer, he can load it up to his own specs. or deprime as he sees fit.
If you want to keep the brass and deprime, just do it slowly with a knock out pin.............Ive never had one go off if done slowly, after having done thousands. If done with a press knock out pin, just make sure that the primer drop port is away from any body parts when pressing primers............Don

Do what Don says. I de-prime with a br sizing die and re use the primers in my fowlers. Never had a blow up--wear glasses.

If you have to ... pull the bullet, empty the powder from the case, and then decap as usual. Only, ... go VERY SLOWLY. I cover the press with a few towels, just in case, but have never had a problem in a few hundred times.

I cannot promise this is safe
I too have deprimed a fey with a die and a decapping pin, I cannot say it is safe but I have not had a problem. Remember primers detonate from a fast sharp impact so you definitely do not want to pop them out fast and hard.

Wonder why so many live primer de-primes?
For me it is usually a set of cases that start separation somewhere or some other flaw that cause decommission.
Sometimes a set of primed cases will need annealing and I will have to pop the primers before applying the torch.
Lately I have had to de-prime some old cases to rifles that I no longer own in order to get the large rifle primers for new projects, since I ran out of primers and was not able to purchase any.............Don

I have never had a live primer fire on decapping in 50 years...

Report from a primer only fired in a rifle can be muffled effectively by taking a large diameter can and putting a layer of foam rubber in the bottom and a layer around the insuide, then just hold the muzzle in the can when you pull the trigger, A towel drapped over the top of the can and round the barrel will help.
Be sure to wet the foam throughly before discarding the can though. I had one catch fire hours later from hot particles embedded in the foam.
While primers usually don't detonate while decapping its best to stay on the safe side and soak with penetrating oil before proceeding.
I would not reuse primers, if for no other reason than it would likely result in inconsistent ignition, plus once seated in a case the pocket may not seal well if seated a second time.

I am equal to you Dennis. That is zero primers firing on de-capping in a century.
I would ask this, what is the extra danger of a primer igniting upon removable that wasn't ignited upon installing?
If it does ignite, what is the danger since it is enclosed?
However, I would use my bomb squad gear if I had any.

Ok
It's winter and obviously these guys don't know anything and i am bored. First off you need a concrete bunker with 1 foot thick walls, then line this with a 2 foot layer of sand, sides, top and all. Kind of like what the BATF requires for explosive storage. Then pour 12 ounces of used diesel oil(preferably out of a Detroit Deisel) into each case and let them set for exactly 146 hours, 12 minutes, and 32 seconds. This oil should have 47 hours of use before using for this application. You stick your hands through the little holes in the bunker and de prime the cases. Wear ear protection. Also make sure your will is up to date, because one wrong move and it is all over.
Do not try this manuver at home and i am not libel in any way. Send the primers to me because they are not useful in any way and are extremely dangerous. Do as i say, not as i do, because i re-use mine as fowlers, i'm a cheap SOB.
If you are not comfortable doing this, or do not not feel qualified, call the local bomb squad and they will help you out.)chill(
If i remember, i will beat the hell out of a couple of primers this weekend from the backside with my decapping die and report back what happened. If i do not report back, either i forgot to try it, or i have "LEFT THE RANGE"

No doubt the buyer would like to have it, so send it with the rifle.
Keep it simple.

Decapping
Primers need impact to go off. It is also best if the impact is on the correct side.
I can't say how many cases I have decapped live primers from. Quite a few. Never had on go off.
It is difficult to answer a question like this. Common sense would dictate that if you jsut gently push it out, nothing will happen.
But, the "chicken little gene" in all of us says only bad things can happen.

I'm still alive
I went out to the shop today and grabbed a old PPC case, put a primer in it an took it over to my Hood Press. I used the same Wilson BR sizing die i always use when de-capping live primers. On the bullet seating side of the Hood Press, I put a piece of steel under the primer of the case and put the Wilson over the case. I pushed down as hard as i could and the primer would not detonate. I tried another primer, same result. So i put another new primer in and jerked the handle down hard enough to shake my bench around it was attached to--NOTHING HAPPENED By then i was getting pretty cocky, so i put in another new primer, put the steel plate on my steel bench, put the primered round on top of it and put the Wilson sizing die on top of that, and grabbed my BFH(actually only 16 ounce)and started beating on the sizing die. I was more worried about damaging the die that i was the primer going off. It finally did, but i had to hit it pretty damn hard. I'm lucky i lived to tell the tale.
Any more questions?)chillD
I gotta go shoot my rail gun.

It froze over Thursday. My Daughter lives right on the river bank and the day before it froze 2 deer went up and down the bank in front of her house and finally jumped in amongst all the icebergs and swam across to Big Island. The ice flow took them a long way downstream. It was below zero, they must have wanted over there pretty bad.
Merry Christmas
