I just had a bad experience with some 9x19 head stamp T these were range pickup, that I picked up with my brass

I found out the hard way that the flash hole is too small to deprime

looks like nice brass but I had to sort through all my brass to pick out the "T" headstamp

If you see them toss them in to the brass recycle bucket

no just a single very small hole in the center

I did manage to punch a few through to deprime ... it then pulled and jammed my depriming pin ... more effort than a very hard crimped primer

and yes these were brass cases
 
The "T" brass I have is 7.5 Swiss and is made by Ruag and haven't had any issues. Never come across 9mm yet at my range though to test
 
Did you forget the SX part of the headstamp? If so...

I had the same problem with some 223 made in Bosnia...I believe. I have never encountered pistol rounds with this condition. They made good scrap. Just remembered, IGMAN was the name on mine, but I don't recall the headstamp. ....catnip
 
I just bought a decapping machine and I read this on their website: “Non-TOX is the new “ Green Tendency.” Some European manufacturers started making cases with a smaller flash hole, and the 1.7mm decapping pin can get stuck. “

So, I bought a 1.3mm diameter pin to avoid this issue.

I think a few of the die manufacturers are making smaller diameter depriming pins available.
 
I have seen those around my range too. Wondering what specific type/load they were from. I assumed they were Swiss because I’ve had GP11 brass with the same T headstamp (for Thun). I’m a total brass Goblin and I don’t want any to go to waste so I actually use my flash hole deburring tool to ream them out. I did break a decapping pin on my hand primer trying to do the first one I came across. lol

The smaller the flash hole, the better the ES and SD.

Absolute statements are pretty silly. I do disagree but it doesn't matter since in this case the small hole is an engineering consideration. At one point DAG (now RUAG) used a two hole system like in a Berdan primed case but with a boxer style Sintox primer.
 
I have some 6.5x55 brass with small flash holes. I drilled them out just enough to accept normal decapper tool. (Lee hand held from a Lee Loader kit. That's all I ever use for rifle cases)
 
The move to smaller flash holes is an attempt to make Boxer ES and SD as good as Berdan - which have small flash holes.

I think this move started in Australia. The target rifle shooters switched from Berdan primed ammo to Boxer and immediately complained of poorer results. ADI did a research on this and found that the difference in performance was due to flash hole size. There was an inverse relationship. This was about 20 years ago. I might have that paper somewhere.

Since then there has been a move to use small primers on cases (smaller flash holes).

One tester wrote:
Immediately apparent is the relatively small spread in values across the 14 models – a modest 18 fps. This compares to a 35 fps spread for 16 LR primers from similar baseline MV levels when I did the exercise for this type, so changing to ‘Palma’ brass and SR primers almost halves the variability.
