What about a 9x25Dillon section

[The_Shadow]

What about a 9x25Dillon section, 10mm necked down to 9mm?  The 10mm guns are quite capable of shooting the 40S&W, 357Sig and the 9x25Dillon with nothing but a barrel swap.


I handload and shoot the 40S&W, 357Sig and the 9x25Dillon cartridges from some of my 10mm pistols with the proper conversion barrels.

Scout camp is going to eat the rest of this week, but I swear first thing Monday I am shipping my Witness Match barrel off for reaming to 9X25.  Gotta get on that wagon after 3 years.

Here are some links to the official Lyman load data:

Well I took apart some of my Double Tap 9X25 Dillon cartridges today for a look see...
Powder used by Double Tap is LongShot

I always wanted to try that loading, but the dies and barrel prices make it a bit prohibited. Would love to hear comments from of 9x25 Dillon users.

9x25Dillon                   9x25Dillon                   9x25Dillon                   9x25DillonAs a handloader it was just something to play with that was unique!  Smaller lighter bullets at high velocity was fun from the same guns.  I will say it is not for everyone...it is a challenge to get all the steps and die settings precise for best performance. 

BTW for those that don't handload this round but wish to shoot it, Underwood Ammo is selling the 9x25Dillon cartridges...

I finally found the barrel.  I meant first thing THIS monday I will ship it off to have it chambered.

Done.

I know this is a VERY old post, but since it has not come to fruition I figured a redux would be appropriate.

Not long ago I started loading the 9x25 and have loaded the .357 Sig since dies first became available. I think that these in addition to the .40 S&W should have their own sections.

The 9x25 does have its own in the wildcat section  https://www.10mm-firearms.com/wildcats/

Unless I misunderstand the difference between a section and a thread...No it does not.

I think of a Wildcat as something that does not and never did have factory ammo, or brass or possibly dies. The 9x25 does or did have all of these so technically according to generally accepted terminology (at least to my way of thinking) the Dillon 9x25 is not a wildcat.

Also a section could include .357 Sig and .40 all of which owe their existance to the 10mm.

Oh, maybe a section could be called "10mm variants"

The 9?25mm Dillon is a pistol wildcat cartridge developed for use in USPSA/IPSC Open guns. The cartridge is made by necking down a 10mm Auto case to 9 mm

I think the commonly accepted definition of a wildcat is a cartridge that has not been codified and accepted by SAAMI or CIP.

Codified? Do you  live in DC? :-)  I'll agree to disagree on what commonly accepted is.

While not a definitive source of info, Wiki contributors mostly agree that a "wildcat" requires custom barrels, handloading and generally massively modding existing firearms. None of this had been case with the 9x25. OTC barrels, ammo, brass, dies all make the cartridge far more a commercial than a wildcat cartridge... IMO that is if one is allowed one here.

I've been long fascinated by the round since Leatham campaigned it but looking at the data above, it seems only a half-step speedier than the 357 SIG and has several large requirements on top of that (larger frame guns, more powder, etc). First time I've
bothered comparing the two charts and  other'n being something odd to play with, I doubt now I'll try it. Thanks for posting the data!
