9x25 Dillon.

[Palladan44]

Im a 10mm guy. Love the caliber. Have a Glock Model 40. Also CMMG Banshee in 10mm. Have my eyes on Delta Elites as well.
Im also a handloader. Dillon 550B with all the fixins.

All I would need to do to use 9x25 Dillon is a new barrel for the Glock, and the reloading dies.

Any comments from folks who have done this?
Is it as pleasant to shoot as 10mm, or is it excessively snappy in handguns?
Does it use 9mm luger projectiles or does it use 357 SIG projectiles?

Looking for some general input this cartridge.
Seeing the very high balliatic energies this thing is capable of out of a high capacity semi automatic handgun, i have to wonder what the negative side to the sweet looking deal is, if any??

Basically the 9x 25 Dillon is very similar to the 357 Sig. Why bother reinventing the wheel when you have a factory load already available.

Fair enough...In my opinion, thats like saying 9mm luger is just as powerful as 357 SIG, or 40s&w is basically the same as 10mm, the parent cases to the 357Sig and 9x25Dillon. NOT the same. There is a significant difference in chamberings, and a significant performance boost. But ammo availibility is very limited, i agree with you, unless you are handloader. This is the "handloading" thread.

Underwood carries 9x25 Dillon ammo. It is quite hot!!

Dillon is the only company that makes dies. I believe Lee will make you a custom die set there is no savings going with the Lee dies.

The one time I've shot a 9x25 Dillon the recoil was more than stout...vicious might be a more apt description. But it wasn't design to reduce recoil, only muzzle flip in a compensated 1911...that is why it was over-gassed

It uses the same bullets as the 9x19mm. I'd highly recommend the RMR 124gr Matchwinners

A quick look at the 9X25 round suggests it might be better off with 357 Sig-like bullets that have a short nose.

I know this is an older thread, but old info is never unusable.

This is all IMO and it works for me, if others found other ways I have no debate and whatever works for you is cool.

First off if anyone wants to load the 9x25 unless you're very fortunate to find a reasonable priced decent stash of native 9x25 brass you'll have to form brass from (not nickle) 10mm. Forget the Dillon dies, the size die under sizes the neck by a lot (also reported in other threads on the web) , necessitating another neck size expansion which led to case cracks.

Again, IMO the 9x25 REALLY wants a long slide. Muzzle rise and flash / blast with faster and medium fast powders with a long slide are minimized. Also bullet selection is a bit fussy to meet OAL with a good crimp to avoid bullet setback and rounder nose bullets work best. I cast and powder coat my own and found what works for me.

If you can find a way to make the Dillon 9x25 (right now they're unobtanium) size die work, a 4 station press will do the job, but I use my 10mm carbo die before the .357 Sig size die to form and reload (after fire forming) a taper crimp seat die.

I'm not loading it a long time but I'm confident enough in my process to form and load several hundred at a time knowing that every case will work in my 1911 flawlessly.

Oh, I also load the .357 Sig, and have for many years, it's a fun cartridge but nowhere in the class of the 9x25 which can easily use much heavier bullets.

Thanks for the info, gnappi.
