Depriming live primers

[pburton]

I made the mistake of seating some primers to deep. I have never deprimed live primers and want to know what the safe way to do this is. I actually did not realize you could actually seat primers to deep until now. Can you safely run them back through your sizing die or is there a better way to do this? Thanks for any info

that's how i have done it in the past, just push them out just like a spent one. some people like to add a drop of water/oil inside the case to prevent any chance of the primer going off but i have never felt the need to do so

Seated too deep? They are supposed too be bottomed out in the pocket!

If you de-cap slowly without impacting the primer it will not give you problems. I also recommend extending the de-capper out a little where the die has not started to size the case, if it were to go off it would only scare the crap out of you and could not build up pressure.

Be sure and wear safety glasses to be safe. and rep;ace the primers with new ones to assure uniform ignition.

You might also make sure that the seating pressure is no more than needed to seat the primer against the bottom of the primer pocket. To much seating pressure can push the anvil inside the cup making the primer short.

3-5 thousands of a inch below flush with case head is what you want

I thought the same thing. But, where these primers are seated, there is no way my firing pin is going to strike the primer. I'm not sure if the primer pockets are too deep. I've never seen this before. It is new Hornady .223 rem brass with Remington 7 1/2 primers.

Post up a pic or 2!

Sounds like bad brass or bad primers!

 

[okie man]

Your primer pockets should be around .115 deep give or take a few thousands at most

Top one seems to deep. Bottom is what I'm used to. It was hard to get pictures to turn out.

And maybe I'm way off and there is no problem.

 

[okie man]

I'd just pop them in the gun, box them up and send the brass back too hornady and get some better brass! That's not right!

 

[pburton]

Ok, so I'm not crazy. I thought this looked wrong.

If you don't have one, buy a case prep machine like the ribs or lyman, and use the proper primer pocket uniformer too cut all of your pockets too a uniform depth. If you get a case that doesn't produce any shavings pitch it because its out of spec and not worth using!

as was said they go to the bottom of the pocket and then a small crush in place.
push one out and measure the depth of the pocket
.1170-.1230 is the spec.
if less than 1230...try one loaded and see what happens you might be surprised.
