I loaded some cases that wont chamber in my rifle.  Sizing die was improperly adjusted.  So I have pulled the bullets and recovered the powder.  What do I do about the primed cases?

I can't chamber them and pop the primers.  Is it safe to deprime with live primers?

Thanks,

Bulldog

Yes, it is safe to deprime them.  Ideally use a universal depriming die, as it provides more room for pressure to go should one detonate.  You can minimize the chances of having one go off by doing the press stroke slowly and gently.  Obviously wear safety glasses.  Most of us here have pushed out numerous live primers and I've never heard of one going off.  Anything is possible, obviously, so be careful.  

Edit:  Then get a case gauge to set up your resize die.

The first couple of times I did it the pucker factor was high, then it becomes routine.  Go slow and easy and it should be no problem.

If it doesn't, don't forget to post picks.

Why not just take your expander out and resize to bump the shoulder back a bit more?

That's what you need to do.  Then get you a GOOD set of calipers and a Hornady - Stoney Point case headspace gauge and learn to set your sizer to bump the shoulder back .002 or .003".

His case necks might need to be expanded after being sized down.

Alternatively, if possible, the decapping pin could be removed and the expander used as usual during resizing.  

Or it might even be possible to back the expander/decapping pin assembly up high enough to work without disturbing the primer.

I have sprayed oil in the case to deactivate the primer before pushing it out.
I didn't know whether you could safely push out a live one or not.

That almost certainly does NOT deactivate the primer.  Do it, put the case in a firearm, and fire it to test.

Slowly de prime, and resize cases, recommend you get a case gauge also.

IMHO.....

It's not safe to de-prime live cases and that's doubly true, when it involves someone else's body parts (whom I don't know).

I might try it........buy why, take the risk?  And.........there is another way.  
_______________________________________________

That being said.........

I'd would just remove the de-capping stem and re-size those cases.  This time.........please check for correct headspace before, going further with the re-loading process.


I use a single station press (RCBS Rock Chucker). You could use a progressive Dillon IF you wanted to. It's a personal choice. But, with whatever press you choose, consider shell plate/shell holder and/or press "flex.”  I use a regular FL size/de-capper die, NOT the small base dies. To begin, FL size and de-cap, 1 or 2 cases for a test. Gauge the re-sized case(s), to confirm that the "correct size" has been achieved.  I use a Forster Products case gauge (the Wilson gauge is also a popular choice).  Insert a case into the die.  The headstamped end of the case, needs to be at or between the high and low cuts on the gauge, to pass. This checks the headspace.  While the other end, is used to check if the case will need to be trimmed (a job for later on).   IF, it’s not the “correct size,” your die setting will need adjustment. Lower the ram and simply screw the die in or out a little. Don’t forget about the lock nut. Then, re-size another couple of test cases and check your work again. Repeat the test and adjustments, as needed.  When you're satisfied that your test cases are properly re-sized, do the entire lot.

For those who don't know about it.........IMHO…………"the secret" to re-loading a bottle neck cartridge is.......a case gauge.  There are many different brands and ways to gauge your re-loads.

Why is it not safe?  What risk?  Eye and ear protection, a glove if you are that uncomfortable.  Just what could happen if the primer went at the bottom of the stroke?  Not much more than a good cleaning of the vent-hole in the sizer die.

I have deprimed live primers on my press many times.  Slowly, to be sure, and with eye and ear protection, but I've also never had one go off doing this.

With that said, Mark's suggestion to remove the depriming stem from the sizing die is spot on.  You can even use some case trimmers on primed cases if the cases wind up growing a bit from sizing.  Two issues to think  about, and they are things you should think about any time you put primed cases in the press: Do not place any portion of your body OVER the case when the ram is up, and wear eye protection.  I do that when loading, and it's smart for anyone to do.

That would probably be OK except you would have to relube the cases.  I would be concerned that the lube would deactivate the primer.

Maybe I went too far...........

How about.........a change of underwear? Fainting? Heart Attack?  O.K.   So, that last one, might be a big leap (if not an exaggeration).  Though, I wish that everyone would consider the possible down side.  Before, they categorically say something is, SAFE.

Just finished a reloading session tonight.

Deprimmed 20 pistol cases that I had pulled the bullets on.

These were reloads given to me, saved the cases and bullets.

Go slow and easy, you can deprime live primers.

Wear safety glasses.

I seriously doubt that a tiny bit of lube on the OUTSIDE of the case could eve get to the primer.  And having tried, tried and TRIED to kill primers, I can assure you that resizing lube is not much of a threat to the integrity of a primer.  They're sealed, it's damn hard to get to them when they're in a case, and most lubes are far less solvent-oriented than say WD-40 which NEVER hurt a primer that I tried to kill...

It is amazing how many believe that WD40 will deactivate a primer.  That belief sets up a significant surprise.

I gave up trying to kill primers a long time ago.  I'd like to come up with some sort of "dummy" primer to close the base on dummy rounds, but I'll live without it.

spent primers should do the trick but for dummy rounds not having anything in the primer cup makes it that much easier to identify it as a dummy round vs a misfired live cartridge

I've thought about seating a spent (and otherwise empty) cup upside down in the pocket to close up the case and also very clearly identify it as a dummy.  I haven't done anything with the idea, mainly because I haven't really found a reason to close up the case of a dummy round...

Having too much time on my hands once, I cut a small piece out of an eraser and pressed it into the primer pocket for a .45 dummy round.  I have no idea where it is now, probably in my SHTF stash.
