Primer Punch Thru

[catmandu]

While depriming some Mill brass, some primers punched thru.

Has anybody any suggestions on how to get the primers out?

If you've gone thru, their gonna be next to impossible to salvage.

What would happen if you tried prying them out with a dental pick?

[fishhawk]

They might come out with that RCBS berdan depriming tool, can't say for sure.

I thought about the Berean tool, but I don't have one.

A dental pick would work with a standard primer, but these are about the toughest I've seen.
The crimps are so heavy the primers are elongated into a round bottom if the pin doesn't punch thru.

I thought about a screw thread. To pull it out.

I figured someone in the group has done this and I could learn from them.

Thanks for the help.

That happened to me just the other day on a PPU 7.62x25. Only happened to one, so I filed it flat and used it to make a dummy. I was trying a new boolit, and I like to have a dummy for each one I use.

Once the primer punch goes through the cup, the primers are really, really hard to remove. I just normally scrap them when that happens. Brass is plentiful, and you can waste a lot of time trying to remove those stuck primers.

Hope this helps.

If you still have some of that lot of brass to deprime, I would soak the casehead/ primer area with some sort of penetrating oil for a few days before doing any more. Most of the ones I have seen that stick that tight are actually corroded in place, a little bit of Liquid Wrench or Kroil and the primers pop right out.

Usually.

Once a long time ago, that happened to me. I had plenty brass but didn't want to be defeated by a mere primer so I got it out. I wound up drilling the cup head out to just under full ID and using a cape chisel to collapse the sides of the cup inward and pick out the remaining cup. I removed the primer crimp via countersink and case was usable.If I was running short on brass, and had a few to do, I might do it again, but with my stash today and the availability of most brass being fairly good, waaaay to much work for one case...

Small drill or a small countersink in a drill on slow speed..... That should do the trick if you really need to save the piece

good luck.

Try a awl or ice pick slide in hole and rock to side a washer over case head will give a block to pry against. May be able to lever then out in this manner. Crimps are part of the problem here but some of the sealants used on military brass tend to act as a glue. I have levered them out with an ice pick on occasion with decent results.

[runfiverun]

you can probably hydraulically blow them out too.
but it's messy.

I just toss em, if they corroded enough to stick a primer that bad who knows what else has gone.

Well here is an update, I found a small diameter steel self tapping screw. USED a driver to set it in tight. Placed the head of the screw in a vise and pried under the base with an open end wrench. Some I had to do several times. The result was 7 out of 10 came out. The others I will make dummy Rounds out of.
They weren't coroded just crimped really well.

Thanks for the advise and good ideas.

A small piece of tubing under the screw head would allow you to draw the primer out with out prying. Think stuck case remover. tubing would need to be big enough to allow primer to clear easily. But would act as screwjack and allow pimers to walk up and out of pocket.

I like the way you think country gent, sometimes solving the problem is the best part.
These cases came out of an estate and RA52s have twice the crimp than usual MillSup.
I will make up something so its ready for future use.

Enjoy your day.

I tried several using motor oil and a wood dowl. The problem I had was as you say the crimp was very heavy. when I cut the crimp out the new primer was not tight. had several that had blow by. that was with cast. I scraped the rest

You would never get the sides of the primer out at that point (once the base is completely gone).

You would be better off trying a drywall screw, thread it into the hole in the primer and let it bottom out on the flash hole and see if it will pull it out.

I would scrap them myself, more than likely.
