Reaming 9mm primer pockets

Probably crimped….50/50 for me with purchased brass…

Have not needed to ream any 9mm crimped primers or depth, on range brass.

The Norma flash hole is undersize.

About 10% of my range pickup 9mm has crimped or staked primers.
The rcbs primer pocket swager is fine for 9mm.
The dillion super swage is overkill for 9mm.
A new PH2 bit in a cheap drill works too, I have progressed beyond such savagery.

I've loaded at least a few hundred crimped 9mm, and none were tight enough to need reaming at all. I would suspect your priming tool of being insufficiently skookum.

I use the RCBS swaging kit set up on a separate single stage press.
These cases have to be swaged, and some PPU PMC, and Speer have to be swaged also.

I have so much 9MM range brass I scrap cases with crimps.

Heck, send me some!

I have never found any crimped brass in the many thousands of 9MM i have loaded which are mostly first fired or new.

What headstamp? may not be crimped, just tight like S&B

I've loaded 100's of S&B with no problems!

I have loaded may thousands of 45ACP and never cleaned or reamed a primer pocket. I recently started reloading 9mm and bought some once fired brass. Now all of the sudden I am reaming primer pockets. Is this typical to 9mm?

I wouldn't really say its typical but its fairly common. After all, the 9MM is our Military's handgun caliber. But like the others have said, 9MM is so common that I put the crimped cases in my trade/give away stash and load the non crimped cases.

I hate crimped primer pockets! Of all the methods to deal with crimps I have not found any single method that works well on 100% of the crimped cases that I have tried.

I use the military crimp remover that I bought for 223 on any case that does not prime easily. About two seconds of effort when mounted in my drill press. Leaves a nice chamfer and works with any small primer case. The best part is no setup or adjustment is required.

I have squished a few Federal primers, but I usually don't throw any
9mm brass away unless it folds up or splits. Now Tokarev is a different matter, I've thrown a bit of it away, but usually not until after I break a decapping pin.

same here

I've found some WW, some Federal and all military primers crimped. I use a Dillon Precision 20095 swaging tool for this. It doesn't remove any material from case. I mark all cases that have been swaged with a dremel tool on case head so I can sort cases already done so I don't do them twice. Some are not readily apparent they are crimped.

I go ahead and take the extra steps to prep military brass, just because I like their lineage

I will remove crimps from .223/5.56 brass, crimped 9mm goes in the recycle can.
