9x25 dillon

I'm very interested in this round. Can anyone give me some idea about the stats on this round
 
I'm not sure what you already know about the round, but I'll cover the basics. It's a 10mm case necked down to accept a 9mm projectile. It's the exact same concept as the .357sig, except it uses the 10mm case instead of the shorter .40s&w case (which had the 10mm as it's parent cartridge anyway). In short, it's one of the most powerful 9mm cartridges there is. Your factory ammo selection is very limited... pretty much DT, Underwood, and perhaps BB. Finding any of these for less than $1.00 per round will be a challenge. Reloading for it isn't cheap either. Dillon is the only source for dies that I know of, and be prepared to shell out $150.00+ for them. Also load data for it is scarce, so reloading for it is not really for the novice. I've read of some using .357sig max loads as starting loads for the 9x25, and they work up from there. Published "Do Not Exceeds" are scarce to find, though, and it's often up to the intelligent and careful reloader to know when enough is enough. I believe Lyman has a few, but covering only a few powders and projectiles (5 of each at best)

That being said, the round launches 9mm projectiles at truly reckless speeds. It appears to work best with the lighter weight projectiles, from what I have read from other's experience. If you are looking to launch 147 gn or heavier projectiles, the caliber has little advantage over 10mm. If launching 125 gn projectiles to 1500+ fps is your thing, then 9x25 Dillon is where it is at.
 
I have a 9x25 barrel for my G29. I bought it out of curiosity and it's a blast. I use Uw 124 XTP for carry because its ballistic is comparable to a very hot 357mag.

357mag has a very good record in stopping threats quickly. They're normally 1450+ fps (which the 357sig cover) but 1700 fps from DT, Uw and BB ammo.

I like the fact that instead of 6 rounds of 357mag in a revolver I have 11 rounds of 9x25 in my G29. It'll do 1540+- fps from it.

That's not to say the 10mm can't stop a threat as quickly as I carry it too.

Oh yeah, they're $18/20rnd from Uw.
 
I have a G20 with 6" and 5.5" ported Lone Wolf bbl's for it in 9x25 Dillon. I loved the idea of 357mag power and then some in a auto with high capacity. Its pretty awesome imho. Other than the worry some of those bullets designed for 1200fps may not hold up at 1700fps. I trust the 124gr xtp and i have some extreme defense 95gr running @ 2,000fps that i know will hold up as their a solid copper bullet. Their what ive carried as SD ammo. Thats alot of shock and they penetrate very well too. Underwood and DT are pretty reasonable. Its a caliber that many shoot pretty well out to 100yds. I havent tryed that yet but i will.
 
9x25 Dillon is extremely loud. If you shoot it without hearing protection, it will cause hearing damage.

It is extremely powerful, but I don't see the benefit to it over 10mm Auto. Performence wise, the 10mm is going to have just as much energy as the 9x25, but it's going to have better penetration and it's not like you're going to be shooting the 9x25 out to 100 yards for self defense.

If you're doing some sort of long range pistol competition shooting, you'd be better off with a revolver than a Glock.

Price wise is going to be the biggest difference for 10mm over 9x25 Dillon. If you reload, which you pretty much have to with either round, 9x25 Dillon will be expensive and time consuming. 10mm is a straight wall case, you have a good selection of loading data, and plenty of people here that can give you advice because they reload for it.

And if this is for self defense, if you want a hot 9mm caliber bullet, go .357 Sig. You'll get it in a smaller gun, you can convert it to 9mm and have cheap blasting ammo for the range, the .357 JHP ammunition is going to be less, and it's going to be just as effective.
 
The 9x25 have more energy than the 10mm and the 10mm will penetrate more due to heavier weight but the 9x25 cause a lot of trauma like a 357mag.
 
Back when this cartridge first appeared I knew a serious IPSC shooter who built a competition pistol chambered for it. I got to talk to him at length about it when I ran into him on the range we both belonged to.

As I finished cleaning up after the class I had just taught, I couldn't help but wonder what on earth was being shot next door. It was, without doubt the loudest handgun I'd ever heard at this outdoor range. It was this IPSC shooter practicing with his compensated 9X25. When he took a break I went over to talk and asked what he was shooting. He told me and touted its incredible power and velocity. He claimed he could get close to 1700 fps with 115g bullets. He also admitted the recoil, even with the compensator was slowing him down compared to his normal 38 Super, and his biggest complaint was that the cartridge was beating the crap out of the gun. He'd had it rebuilt once and said it was going to need another rebuild soon. I asked him why he bothered with it and he said it was mostly because he had so much money invested in it he felt obligated to shoot it occasionally.

Any interest I might have had in the 9X25 was pretty well killed by that range conversation.

I think the question we should be asking Eod1 is: what does he intend to use a 9x25 Dillon handgun for.

If Eod1 is just looking for general information about the ballistics, recoil, accuracy, etc. of the gun and not whether it's a good choice for what he intends to use if for, then carry on folks.
 
I wanted to hear other peoples opinions first before I came out with mine. I wanted to hear what experiences everyone else had with this round. You guys are right when u say it's a violent gun to shoot. I have a motified G40 and a motified g20 that I work over pretty hard. I have a dedicated 1050 dillon that reloads my 9x25 for me. I had case Gauges made for me using brass that came out of the dillon full sizing die and blue prints for the case.
 
My barrels are from Lone Wolf. They are the Alpha wolf barrels. I polished and deburd the ramps and chambers. Slides have been lighten and I run a custom 24 pound recoil spring. They run very nice and with a silencer very nice as well. No problems so far. 10,000 rds into it. I expect to change barrels around 15k to 17k.
 
EOD welcome to the forum if no one has told you already. Have you chronoed your loads by any chance? I'm getting a G20 (at some point in the future anyway) and am very interested in 9x25 along with 10mm. Interested in hearing about your recipe, especially hearing that you have a fairly high round count (for a hot rod caliber, at least).

The Winchester Luger 9x19 +p+ round is way out of SAMI specs. I would say you are stressing your Glock breech face to dangerous pressure levels that could have catastrophic consequences. It does make for good business for us gun smiths and hospital emergency rooms though. For what it's worth, pushing anything beyond it's initial design specification is just a real bad idea in my opinion!

I have had the distinct pleasure of knowing some folks that thought they could change a tire on a car while it was going! I hope you picked up on the past tense when I said (HAD)!

Not sure of how this relates to 9x25 Dillon. 9mm Luger is not the parent case (10mm is), and I've read or heard of no one shooting 9x25 out of a pistol originally designed for 9mm.
 
Did they fix the problems they were having with them in the 80's. Frames cracking around 500 rds. I always wanted one but I was afraid of that problem.
 
The 'cracking' was at the slide stop. They just took that part of the frame off from future Colt 1911s. They all now have a little gap where the slide stop fits into the frame.
