Default Found primer walls in my brass

I was resising some .223 I had shot out of my AR. As I was cleaning the primer pockets I noticed on 3 or 4 pieces the walls of the primers were still there. The heads were gone. 55gr Barnes TSX and 25gr of CFE 223. Max for this load is 27.6. CCI 400 primers. I know I should have but I never looked for pressure signs like flattened primer.

Has this ever happened to anyone else and is it something I should be concerned about?

Steve

Are these reloads of yours, or military ammo, that could have the sealer alongwith the crimps that the military use ? Bill K

Now I really wonder what would cause the side of the cups to separate, never seen or heard of that problem. I really desire, as you do also, to know why. Keep us posted on what you find out from someone with knowledge. Bill K

Did you notice anything different when pushing the spent primers out of the brass, like more resistance?

I've had that happen over the years, long enough ago to not remember the exact circumstances. Being a diehard cheapskate, I ground an old tap to catch the remaining primer and was able to drive them out through the flash hole. Kinda frustrating when you're trying to prime cases -- otherwise, no harm, no foul and I have no idea what causes that condition.

Among the many "mistakes" and plumb stupid screw up's I made while trying to learn the reloading game. I over loaded some '06 where the primers backed out a bit or I think they did. And formed a flat edge around the rim of the primers.

When decapping the flats came off and left the rims in place. As I recall, or think I do, they were down in full depth. That was over 50 yrs ago so it's hard to be sure at this late date. That's the way I think it was though.

I made about every mistake that could be made those days as I had no one to guide me. I was 14 when starting out in 1958.

Nope don't remember anything different. I noticed it when I tried to use my primer pocket uniformer. I went threw my scrap and found them. Took some work lol. 4 rounds out of 40. 3 PSD and one LC.

Did you swage, or chamfer the pockets ?
I've never seen this either.
How did you seat them ?

I use the primer pocket uniformer and reamer on the primer pockets. It cleans them up nice. I have the Lyman Case Care set.

It must have something to do with the brand of brass as these were the only LC and PSD cases I had. The rest were Winchester and R-P.
