Well I took apart some of my Double Tap 9X25 Dillon cartridges today for a look see...
Powder used by Double Tap is LongShot
9X25 Dillon DT performance August 6th 2008
Bar-Sto Match Grade 5" Barrel test from S&W 1006, the 5" Barrel is too short to achieve the higher velocities.

Do you shoot one?
If so, is it compensated?
Man what a screamer. 8)

Seriously! That is scraping rifle velocity!
BTW there is more to the post that I could not get to copy over, working with Grim Reaper to get things ironed out.
Yes, I shoot from the S&W 1006 with a BAR-STO match grade 5" barrel and the Glock 29 3.78" both non compensated barrels.

History of my 9x25 project...The 9X25 Dillon conversion project started back April 17th 2008 with the purchase of a Bar-Sto Match Grade barrel for my S&W1006 from Mike McNett of Double Tap. The barrel arrived April 21st, 2008 and inspection showed it needed to be fitted to the slide and frame of the S&W1006 before anything else. I took my time carefully getting the fit correct to get proper lock up while in full battery now it is June. I searched around looking for a Gunsmith who could do the final chamber reaming and was contacted by a very nice gentleman from The Gun Works in Ohio, from one of the forums who said he has the reamer and has done quite a few. He advised he could do the job, so mailed out on July 24th, 2008. I received the properly reamed and head spaced barrel back August 5th and was shooting it for the first time August 6th, 2008 with some of the rounds I purchased from Double Tap.

I spoke to STI last week to see if they would fit a 9x25 barrel to my STI Perfect 10, the man in the shop said they used to but have not done one since the custom shop was closed (last year) but I should call back in a couple months when the Custom shop is re-opened.

Just ask them to fit a 9mm or 38 super barrel. Then ship it off to Ohio to be reamed.
The 9x25 Dillon performance begs for the longer barrels, 6" + barrels are better than the shorter ones I am currently working with. I have a 6" 9x25 custom barrel scheduled to be made for my S&W1006, however that has stalled becuse the machinist lacking access to CNC machines due to current production runs.
There maybe a Glock 20 (4th Gen) in my future and may go "Hog Wild" with that setup. May build it with the LWD long slide, barrel is 6.61 inch length (or custom barrel) and the compensator... 8) Time and the most important part "$ Money $" will tell!

Makes sense. I'ld think something like a custom Bar-Sto of around 7.5" would be really slick for the 9x25 Demon...I mean Dillon. :D
When I first considered getting into the 9x25Dillon I didn't find much data except for what was on the Glocktalk site in the 10mm handload section. Then I started to communicate with a nice fellow on one of the forms, he had mentioned about some stuff about the cartridge that was said to be the notes of the people at Dillon (Jay Phillips,Randy Shelly, Arnt-Magne Myhre)?
Long story short this nice fellow sent me copies of the data to help with my study of the 9x25Dillon. Many of the notes were not clear as exactly what cartridge was being tested although it was suppose to be 9x25's. However being a Blue Dot fan I decised to start with it because I was most familure with Blue Dot.
Earlier this month (7/2012) I snagged a copy of Lyman's "Pistol & Revolver Reloading Handbook" second edition from "Evil Bay" because it had an article about the 9x25Dillon specificly and also some limited loading data, that I already had obtained from another nice person. These loads were developed around guns using comp'ed barrels using slower burn rate powder to generate large volumes of gases to make the comps work.
I'll try and post some scans of the info...
I Updated the first post with some scans from the Lyman book.
Hope people find them useful. ;D
How come I'm not seeing 147gr load data above? Maybe I'm blind. Just seems like the 147s would really shine at maybe +1200fps. Especially the XTP having the boat tail base.
At a guess...
The cartridge was originally designed to make major for IPSC in 9mm and drive compensated guns. For those purposes a lighter bullet has many advantages and no disadvantage over a heavy one. In speed shooting lighter bullets are just better. That is why they came up with the power factor thing to begin with, to compensate for guys running lighter and lighter bullets and loads.
The cartridge never really took off, even in IPSC. The result is that there is very little load data and what their is was targeted at the original audience.
The 147's can be used however they occupy internal space and displace the amount of powder. The 10mm can probably push the 155's and for sure the 135's faster. There are trade offs, and yes many of the guys are still working with various loads and powders developing loads. The 357Sig cartridge helps here some as a place to start with some powders.

I see what you're saying.
I just ordered a build 9x25 long slide, 2011 frame, threaded barrel with this compensator
http://www.egwguns.com/cnc-compensators/cnc-8-port-6-chamber-compensator/
This is done by fusion (custom build). They will also make the barrel (I called several places only bar sto replied that they would do one (as it is not listed ).
This whole thing costs like a small motorcycle
Looking forward getting it at least this year...
just subscribed to this forum to get updates on the development.
platform, Are you going for a special gun or competition race gun? While it sounds as though you're paying some premium monies, this does sound like a great build. Fusion does make some great guns.
Do you handload or intend to load for the 9x25Dillon cartridge?
Good luck with the build, please post pictures and a range report when its done!
Regards
wouldn't mind seeing a 115gr barnes tac xp bullet from 9x25 :)
Yes the Barnes tac xp bullet in 115 gr would be nice. They are as long as the 125 lead core and probably run along at near the same speeds as the 125's but will hold together much better in various medias.
I have some Barnes tac xp 125 gr bullet that I am going to load when I get some loads dialed in, they are as long as the 147gr lead core counterparts.
At the moment I am loading some Sierra 115 JHPs...
Sofar it is just a 'special gun'. My skill is not there to compete. So I am not using any 'rule book' to decide on weight/components etc.
My goal for it to be 'over built' and reliable for the cartridge in it hottest load
My second goal is for it to be shootable, and the 3d (lesser importance) to be good looking even as years pass by.
I think Fusion can do all of that for me .
Also one of my asks was to test my build with 50 rounds of 95g doubletap 820+ ft/lbs (and save the brass) -- so expecting perfect function there as well
I do not reload now, but overtime as time facilities and time allows -- will definitely do that. So far when I shoot I just save brass for the future (and will participate in group buys for 10mm/9x25 brass as they are being organized)
Once I get the build would like to hook up with somebody local to test the speed/penetration/brass friendliness/100 yards shoot-ability of the build.

I hope they are doing yours as a ramped barrel configuration for the added case support. Some have taken 38Super barrels and reamed the chamber to handle 9x25 with good results.

I like the way you think. Should end up being one awesome platform!
was told recently, that my gun will not be ready till December. So the total wait time for this fusion build is now set for around 24 weeks.
(not sure exactly why, as I doubt it takes that long to build it and make the barrel, but ion bond finish takes very long wait time). While not happy about it, will wait till december.
I guess quite a few of Bob's clients order $3K guns -- so mine is one of many in the conveyer.
Will update here when I can finally get my hands on it, also hope by that time underwood will have 9x25 stamped ammo :-)
Still pretty excited :-)
36 weeks sofar. My gun is still not ready (I do not think they even applied the ion bond finish yet).
So no particular progress to report.
I have been checking the underwood site for 9x25 -- nothing available for 3 months now.

OUCH.....

I got some trigger tome with the new G-20SF using the Lone Wolf Dist. 6" 9x25Dillon barrel and got to see some real good numbers today...
Dropped in the LWD 6" 9x25Dillon barrel and got the numbers I was looking for with my handloads...
121 gr Zero JHP's 0.356" over 10.5 grains of LongShot
1610 fps case expansion 0.4280"
1591 fps case expansion 0.4280"
1652 fps case expansion 0.4280"
1648 fps case expansion 0.4280"
Primers moderately flat
110 gr Remington JHP 0.357" over 10.5 grains of LongShot
1738 fps case expansion 0.4280"
1732 fps case expansion 0.4280"
Primers slightly flat
125 gr Lyman Cast Devastator HP 0.356" Zombie Green painted
1642 fps case expansion 0.4275"
Primers moderately flat
Nice! In a bottle neck case like that I bet Alliant's Power Pro 300-MP would do really well. Maybe Lil-Gun too.
Well maybe not, (PLEASE Do not take this wrong or as an attack on you)
I have friends who have tried Alliant's Power Pro 300-MP in 10mm as well as other cartridges, it is too bulky and you can't get enough inside to perform, the same is true for H-110 and Win296
Here are the dismal results from the Win296 which I wasn't going to post because of such poor performance...
121 gr. Zero JHP over 14.2 grains of Win296 with CCI350 primer as tested from the 6" tube:
1338 / 1217 / 1303 / 1204 / 1265
case expansion 0.4275" / 0.4270" / 0.4275" / 0.4270" / 0.4270"
Primers moderately flat
Yes, in 10mm Auto they do suck. I tried it besides already knowing better. 9x25 Dillon is an entirely different animal being that it uses a bottlenecked cartridge case, which of course I know you're well aware.
What I know is that H110 works awesome in 357SIG if we're just talking about velocity. That said, it would seem reasonable that Alliant Power Pro 300-MP (a faster burning powder than H110 or W296) could work really well in 9x25 Dillon, especially from your 6" tube.
I could certainly be wrong. By the same token I would also certainly give it a try. But that's just me, certainly do what makes you happy! 8)
If I ever come across any Alliant's Power Pro 300-MP or can get a sample from any friends I will give it a try in several various cartridges...But to buy a pound out right may not happen right away. ???
BTW I added the case expansion to the recent tested loads. The LWD 6" barrel has a great chamber and support, it was a good investment already being into the handloading of 9x25Dillon cartridges. ;D
Just got my barrel back from The Gunworks in OH, they did a great job on it; it was a barrel I ruined reaming it out to 357 sig and going a few thousanths too deep. I have just finished fitting it to my AMT Javelina Longslide, which now shoots 357 Sig, 9x25 Dillion, 10mm, and 38 Super.
I wanted to shoot this cartridge for power, not velocity, so I am going with 147g TCL and maybe 8g blue dot. I load my 357 Sig with 6g Herco and a 147g TCL - it is a tack driver! Can't wait to try out my new barrel, and work up some loads. It is all about the accuracy, not just how fast you can send lead down the range.
Countermeasure, welcome to the forum! Glad you found Mr. Van's work from The Gunworks in Ohio, to take good care of your needs! Please report on your results with your loads, its always good to learn how others are doing...I will agree with the accuracy. However we must study the upper ranges of performance to see if and how they work too, as we look for a perfect balance.
If you have any questions or just want to bounce around some ideas, PM me.
Best regards! ;)
Just reviving this thread in my quest to start a 9x25 resurgence!
I have the 6" Glock 20 9x25 Dillon barrel. Have some ammo, and now researching loading it. Found this thread looking for Longshot loading data. I don't want to go 90 grain bullets, prefer 124gr and above.
