Anyone on here shoot 9x25 Dillon

[JROC]

If so what do you think about it? How do you like it? Is it pretty fun stuff to shoot? I'm thinking about buying a 9x25 LWD barrel for my G20SF.

Look at the ballistics on this stuff:

One of my favorite things to do while shooting is to shoot clay bricks and thinks like that with my G20 using full power 10mm loads. I imagine some of those 9x25 95gr FMJ rounds could really do some damage traveling at those velocities even being a much light projectile than what you fire from 10mm.

BTW I'm not asking about this for a practical SD round, but just something to shoot for fun.

Thanks,

Jesse

It is a bit of a specialty cartridge that got bumped out of copition some years back. Might be cool range/fun gun but limited to bullet design and weight for hunting . Bullets are also the same made for the 9mm and may not act the same as a defence round. Faster for sure.

It is an impressive round.

While the 10mm is already flat shooting the 9x25 is like a laser, it is so flat shooting it hits the same point of aim for quite a distance.

The round also has some serious penetration, it is close to a PDW round. Performance is a step above a really hot 7.62x25 (9x25) Tokarev. And the Tokarev is known for penetration.
Or for a more American comparison take a .357 Magnum, they use similar bullets in some popular weights (like 125 grain). There is people that swear by .357 Magnum full power 125 grain loads, and 9x25 Dillon gives you that in an auto with about the same sectional density. While the 9x25 Dillon gets even faster with lighter bullets.


The downside is very severe muzzle blast for a pistol. Recoil is fine and less than the 10mm, but the muzzle blast gives the perception of more than there is.
It was actually originally intended to have more gas than necessary to act on the compensator in matches. While it works fine with regular barrel length this also means it can be loaded to greatly benefit in the form of velocity from increased barrel length putting that gas to work.
(It would make a great carbine/SMG round. You can get the performance of a .30 Carbine in a much shorter barrel.)


Another serious and related downside is noise. The round is extremely loud. So loud you may need improved hearing protection if you use standard just adequate levels of protection.
The lighter full power faster loads are louder than a .357 Magnum.
The noise is at a level where hearing damage from frequent shooting even with light hearing protection is likely.
While you can work around this at a shooting range by using better hearing protection, the noise level without hearing protection is so high that it counts heavily against it in a self defense role.




However you can also download the round to any level you choose.
From .38 special/.380ACP to .357 Magnum levels, and you can use typical cheap 9mm bullets to reload with. (Severe changes may require a different recoil spring.) Lower velocities essentially turn it into those lower rounds, with similar reduced report and blast.

The 9x25 Dillon is loud and has a lot of blast by design. It was designed to push a lot of gas down the barrel to power the compensator of USPSA Open guns...they had very little muzzle flip.

If you are into unusual calibers, but want a little more utility, consider the 9x23 Winchester

Thanks guys for the great info! Y'all are making me want this round more and more.

I think I'm about to place an order to DT for a LWD 6" barrel, and probably some of their 95gr FMJ 9x25 rounds.

I'm pretty sure that all that's needed to fire it in a G20 is a barrel conservation that will drop right in right? I have a Wolff 22lb recoil assembly in the gun for full power 10mm load, and I assume it would work great for these hot 9x25 rounds?

9mmepiphany can you fire the 9x23 in a barrel designed for a 9x25 in a Glock 20?

The 9X25 is the only handgun round that I found to be painful (to the ears) to be around, and that was when someone else was shooting it some 20 yards away. And yes, it was a compensated, Open Class IPSC pistol. The shooter told me some months later that he gave up on it because of the noise and because it litterally beat the gun to pieces in a few thousand rounds.

I can't imagine spending a lot of time shooting that cartridge without damaging you hearing. Not kidding, it is that loud.

Hmmm...

Maybe I should wear both ear plugs and earmuff's when firing it. I'm all about ear protection after seriously hurting my ears a few months back by not wearing ear protection and shooting 50 rounds of .45ACP, and 25 rounds of full power 10mm ammo. That turned out to be a really stupid move on my part, and my ears were ringing for over a week.

My Mistake...Brain fade...disregard

9X23 isn't very practical in a Glock.

The 9x23mm is a rimless .38 Super

.38 Super Comp is a rimless .38 Super.
The 9X23 is a rimless, tapered case with similar dimensions to the 9mm Largo.

9mmepiphany can you fire the 9x23 in a barrel designed for a 9x25 in a Glock 20?

No!
9X25 (9X25 Dillon) is a bottleneck case based on the 10mm auto, like the 357 sig is based on the .40s&w.
9X23 would burst in the much larger chamber of the 9X25. Headspace is N/A in this case.

It isn't recommended, it headspaces on the case mouth and would be 2mm too short to headspace correctly for good accuracy.

It was a good guess though.

Another option

Get a 357 SIG barrel for the G20 with an appropriate throat. Load it to 10mm OAL. It isn't too far off 9x25 Dillon in terms of capacity. The lighter bullets might benefit from the 9x25 though.

357 SIG is relatively common brass-wise, and it uses small pistol primers. The small primer thingy is nice because the brass is stronger and you can use small rifle primers.

In fact, it wouldn't surprise me if you could load the long 357 SIG to higher pressures.

 

[hardluk1]

With some barrels companies you can shoot 9x23 in 38super but not in 9x25. Difference is straight case to shouldered case. Thing 100 brass and 9mm brass. Don't get the 9mmbullets and 357 bullets mixed up. Even though there is only 1/th difference in width they are designed for a different velocity and energy level. Shooting regular 9mm bullets in the 9x25 dillion would tents to take HP 9mm bullets to or beyond there limits. Wonder if you could cast heavier and harder lead bullets for a 357 and swag them!! Naaay, shoot the 10mm then.

this.

many don't realize that almost all loads for this round are simply 9mm bullets that disintegrate at the dillon velocities, sacrificing penetration.


velocity and energy are generally nothing more than marketing tools for these obscure rounds.

 

[atblis]

There are plenty of bullets that hold together just fine. I can't imagine anybody would buy this round with the intent of shooting factory ammo out of.

 

[JROC]

Yeah that's one reason I order FMJ rounds instead of hollow points.

From my understanding even the 10mm 125gr JHP rounds that are rated to travel @ 1600fps are being pretty taxed on holding together while in flight.
