Upside Down Primer

[Kwikvette]

You can deprime a primed case; just run it slowly and push the primer out.

This is of course after you've pulled the bullet.

[Gryff]

Drop magazine, unload gun, and check primer. In the bad lighting, I couldn't understand what I was looking at. Then I realized the primer is in backwards.

This is why I use the plastic ammo boxes. You can see instantly if there is a flipped primer, and also get a pretty good idea if any rounds have high primers.

One more reason why I turned to hand priming.

[CSACANNONEER]

back to the danger situation... a drop of oil will kill the primer.... so as a poser above commented, add a drop of WD40 and set aside until its time to reload again

I would NEVER trust oil to deactivate a primer. I know too many people in the know who have done tests with, water, and different oils trying to get 100% positive results and, they have always ended up with primers that will still fire even after being for hours, days, weeks and even months.

I must the only person who has gotten an upsidedown primer on factory ammo....let alone reloads.

Nope, that's why I already posted this:

Yup, primers can flip during the priming process on ANY machine.

The "ANY" does, of course, include systems used by both large and small ammunition manufacturers.

I remember the first time I set a primer upside down in a piece of brass. I prepared to take out the primer with my single stage press wearing extra goggles and my shooting ears...

To my disappointment...nothing happened. Not even a spark.

I insist on either goggles or face shield when reloading for
everyone in room .
I have had so many problems with primers that now I only
use CCI .
pistol cases are deprime by hand - rifle on loadmaster .
All are reprimed by hand .
I to put reloaded cartridges in plastic boxes to check primer
height .
Then they are put in magazines .

LOL OP. First of all, the piece of brass is worth like 10-15 cents. If you are uncomfortable with playing with a live primer don't.

But... really all you have to do is pull the bullet and run the brass back through your machine's de-primer stage. Pull gently - don't hit it and it will de-prime easily.

This. Been loading for 40 years, and have done this more than once.

I average 1-2 per 1K rounds loaded. I use a hand deprimer to pop it out. As for factory AMMO with inverted primers-----we had to inspect 1.8 million rounds of linked 60 AMMO for inverted primers. Humping 120 pond cans of AMMO----took a crew many months. By the way----we found 12 inverted primers out of 1.8 million. I found one of them. I.Y.A.A.Y.A.S!!

[Sir Toast]

WHY?!? Toss it.

Also, I haven't ever had a primer flip when reloading, but strange things have happened.

[jericho89]

With the Dillon 550, is it possible for the primers to flip during the loading process? Or was it me?

.

In the hundreds of thousand rounds loaded on a 650 over 20+ years I have NEVER had a primer flip in the machine. The only way that would happen in the primer tube is if yours was so worn out it does not hold them tight (I have never changed mine) or you have the wrong tube in. If it were able to flip in the tube there would be a much larger percentage of flipped primers.

Now I am not saying I have never had a flipped primer, but it was due to operator error. Either picking up one upside down, or not putting the pickup tube tight against the primer tube before you pull the pin and dump them.

As stated you should inspect each round before you call them complete. I do it a hand full at a time and simply look at the bottom of 10-15 cases for a second to make sure it looks fully seated and correct side in.

You should also make it a habit to check your ammo as you are loading your mags, remember you can get sideways and upside down primers from factory ammo... it is rare, but they do slip by their QC every now and then.

Years ago I had problems with flipped , bent , had them
blow up in tube , primer feeder / slider chute . Back then
I was buying what ever was on sale . [ mid 70's ]
Any way , I now only buy CCI and hand prime .
I think a guy at the range had a 550 - he had 2 chutes
blown apart - and a primer stuck in tube .Dillon replaced
the parts , but the time he spent waiting really pissed him
off . He was not impressed with my loadmaster , but came
back 3 times to reload while waiting for parts from Dillon .
He sold the Dillon and bought a T-7 .

Im new to reloading, I'm in a state of being very cautious, Ive loaded 44 mag, and recently 45 acp, I use a powder lock out die, I can feel whats going on (Dillon 650) as I'm reloading, when I'm done, I sit down in my big fat easy chair, with a sizing nogo gauge thing, I check each one and look for proud primers and yes that infrequent upside down primer, I set the rejects aside, and box the rest.

today I casted my first boolits, 25lbs of 358429 to be exact.

[bruce381]

nice 38 special and 357 boolit have fun

Sorry, I don't think that's "the only way". I've seen primers flip as they were fed into the priming tube and after they have left the priming tube.

If they are flipping going into the priming tube then you need to adjust how you are loading your tubes. On a Dillon (which is what he is asking about there) if you hold the pick up tube straight and tight against the primer tube before you pull the retention pin they will not flip.


If they are flipping after they are leaving the priming tube then your machine is out of adjustment.

I have 3 Dillon machines, have loaded over 20k rounds a year and have maybe flipped 2 primers a year (and I can not remember the last time I had one flip. If your technique is good and your machine adjusted correctly they do not flip.
