Primers not popping out on Armscor 9mm

[pinne65]

9mm range pickups stamped "A USA". I have the hardest time getting the primers to pop out. I've lovered the stem in the sizing die so much it almost touches the bottom of the case inside. And the primer popper must be sticking 1/2" below the case.

What am I missing?

round your decapping pin a little. some primers grab a little tighter. it happens a lot.

Ooh - you mean it's getting pulled back in?

Yep. I've had that happen myself.

 

[pinne65]

How weird I've never had that happen until biv started reloading 9mm.
Thanks for the info!
It was driving me crazy

Certain manufacturers are more susceptible than others I've found. I think heavily crimped primers are a big part of the problem.

Great idea! I've been having a bunch of trouble on my Dillon with rcbs dies. I do a full stroke, nothing feels different but the primer is still there. Gets annoying at times

Now I'm thinking - I did replace the decap pin and I have never really paid attention to the thickness of those. I'm mostly reloading using large primers.....

RCBS dies use two different sizes of de-capping pins. Since you've replaced it, I'm pretty certain you have the right size pin in the die or else...& I'm guessing here, the pin would pull out of the die.

I had some 9mm range brass with a red coloration around the primer pocket... could not get the primers out... must be those crimped primer pockets. Threw them all out! Not worth the trouble!!!

Red is usually a sealant. Doesn't mean it's not crimped too though.

May indeed have been both... IIRC there was a ring around the primer pocket on most if not all.

I've got several like that (at least with the red ring). S&B is one brand I have with that.

"Primer pull-back" I think this is called. I had issues with it on .223/5.56mm. Especially if there was a grit of corncob media stuck in the flash hole. The tip of the decapping pin would grip onto the primer and draw it partially back into the pocket. Dyjital suggested rounding it. I went the other way and found that grinding it more to a point gave the pin less purchase. Whatever works. Could also be that a new pin isn't as smooth as a used one that has a less grippy surface.

Weird, I had the same problem with some range pickups the other day. Same thing but on a few .223 cases, it was like the primers were extra long so I adjusted the decapper rod deeper and still didn't punch it out. I had to pull the shell holder ant use a small flat tip screwdriver to pry it the rest of the way out. I didn't look at the headstamp either, puzzling to say the least when on robot mode recapping hundreds at a time....

I really noticed it using the Dillon XL650. Don't recall ever having this issue on the ammomaster2000. Could be just coincidence.

I'll have to check to see what die I've got in the Dillon. I believe it's a Dillon die.

I've found that red means DANGER on ammunition. There have been many times with 5.56 AND some .223 that I've had to readjust the pin due to excess pressure exerted to punch out primers that are crimped.

Military brass? I believe its for sealing against moisture. Squirrel Daddy makes harden steel decapping pins for this.

RCBS has some spring loaded decapping rods that work well. Should screw into most standard dies etc...

Thanks - that helped! Not a100% but much much better. I'll do some more rounding also.
