View Full Version : 9x25 barrel and need ammo suggestions

12-26-2011, 22:14
Hey all, a good friend of mine gave me a Lone Wolf 9x25 conversion barrel (20SF) for my birthday. Can anyone confirm that Double Tap is the only source for the 9x25 cartridge? I currently hand load for the 10mm, but I won't be a able purchase the Dillon die sets for some time. I'm looking forward trying out this cartridge soon. Any suggestion if I have to order ammo from Double Tap? Thanks!

Currently yes the 9x25 is only commercially avalible from Double Tap. I would suggest getting a variety pack to see what you like. You didn't mention what barrel length, but performance is best from the 6" and longer barrels.

A word about hand loading, Dillon makes the dies which have dual cabide sections one for the 10mm and one for the 9mm. Proper head spacing and tight neck fit are essential for performance. I shoot from S&W 1006 5" and G-29 3.78" as my current platform.

As far as I have found double tap is the only factory produced 9x25. I have looked around the net for awhile and its mostly a reloader project. I'm set on getting the dies as soon as I finish tweaking the pistol. Wish some body else besides dt was the factory

Saw Shadow's post in the reloading forum. Underwood Ammo is now offering 9x25!!

Kevin has none in stock at this time from the add. I haven't spoke to Kevin, but gathered that he will be using 10mm brass until, enough buyers are intrested in 9x25Dillon ammo or 9x25Dillon brass to make an order for the properly marked 9x25Dillon brass. I had posted about 9x25Dillon brass before also, I wrote Star Line about a special run of 9x25Dillon marked brass (with small primer pockets) or any head stamp you wanted. Here is what they said...

The minimum quantity for a run of 9x25 Dillon with a small primer pocket would be 100,000 pieces. The price would be $136/per 1,000 and there would be a $750 tooling fee for the headstamp (What the headstamp reads would be your choice). This would be straight, un-necked brass.

Therefore I would think that Kevin would be subject to the same should he wish to have properly marked brass.

Even trying to do a group buy would be tough to obtain 100 buyers getting 1000 pieces each...:shocked:

$13,600.00 100K brass
+ $750.00 Tooling for head stamp
$14,300.00 Total cost

We will have to see how this shakes out...

Why can't you buy the 9x25 dies? You can get the set from Dillon for less than you can buy 3 boxes of 9x25 from DT, and DT isn't likely to meet the velocity claims they advertise anyway. What powder are you using for 10mm? I developed a load for 90gr XTP's using Longshot, that sends them down range @ 2050fps in a 6" barrel. I'm trying to find the time to work up 124gr XTP's with Longshot as well, but for now loading my rounds for competition is in the front seat. I should be able to get them up to 1750-1800fps. I have also done some workups with Blue Dot, but I got much better performace with Longshot & used less powder. My giganto-fireball load is 14.5gr Blue Dot under a 90gr XTP with CCI300's, but I use CCI350's for my Longshot loads.

Since you were given the barrel & you already have a reloading setup, I strongly suggest getting the dies now. Handloading is the only way to fly for the 9x25 Dillon.

Looking to pick up the dies soon, but wanted to try shooting some factory spec ammo to get a feel of 9x25 and what to expect. Just excitrfed that somebody else is offering 9x25.

I'd like to know if they are actually pressure testing this round or copying someone elses loads or data. After taking down the Double Tap 9x25 rounds, I documented what I found and loaded it and tested what I found with the exact same velocity results from my guns.

If they are pressure testing what specs are the using because it is not published by SAAMI? 35700 PSI? 40,000 PSI? More??????

The reason I load my own is cost savings...Underwood IMO has a reasonable pricing for his products, the killer on many mailorder things is shipping. Shipping & Handling charges exceed the value with many suppliers and kill many purchases for me.

Hey are you guys using your stock recoil spring or a heavier one?

07-04-2012, 19:17
I'm using an extra power in my S&W1006 5" 22 lb and 21 lb in my Glock 29 3.78" for the 9x25Dillons...

Ok thx. Do you think the Gen 4 G20 can shoot 9X25 reliably stock?

07-05-2012, 23:44
Having only shot 9x25 Dillon through a G20LS w/20# & 22# springs, I can't say for sure. However, being that my 90gr XTP @ 2050fps load recoils less than my hot 150gr/180/200gr 10mm loads, I would say it should eat up the 9x25 with no problems. Especially since a ton of guys shoot hot 10mm with the stock GEN 3 RSA. My GEN 4 G21 uses the same RSA as the GEN 4 G20, and it is noticeably stiffer than the GEN 3 RSA. It probably isn't rated as a heavier weight spring, but the dual spring system has more preload, so the initial push should get slowed down more when compared to the GEN 3 RSA.

Ya that is what I was thinking. If the 4th Gen G20 can shoot full power 10mm (Doubletap, Underwood, ect) all day long, then this gun should be able to shoot the
9X25 as well (in stock form). What is the pressure of this round anyways? Is it pushing 40,000psi like the 357sig?

They should work as the only changes that I understood were the grip texture and the grip panel inserts. I think the recoil rod system was reworked as well for the better.
