9x25 Dillon

[Tea Man]

For months I've been wanting to try the 9x25 Dillon with my G29. Last month I thought WTH, get it. I ordered an LWD 9x25 barrel and some ammo from Underwood.

After my first session at the range with this caliber I had to replace the recoil springs to stronger springs so I ordered a 21# set form Wolff because it is non-captive. I also ordered another box from Uw.

It is much better and I gotta tell you, this is a darn powerful 9mm cartridge (10mm necked down to 9mm) and puts you above the 357mag territory.

The 357mag has a proven record of stopping threats so I feel confident carrying my G29 loaded with the Uw 9x25. The Uw round rated at 1700 fps for 796 fpe does 1522 average out of G29 and produce 638 fpe.

I like it. :smile:

How is the recoil in comparison to hot 10mm loads, such as those from Underwood?

Do you have any practical application in mind or is this just for fun?

 

[Tea Man]

pretty much the same as Uw 10mm 180 and nothing particular in mind, just SD and range. :tongue:

SD, meaning self defense?

SD, meaning self defense?

Yes.

 

[bofh]

Yes.

Against what? I haven't seen any gel test videos of such hot 9x25 Dillon. For a JHP round, there is the risk that it would disintegrate due to the high velocity and not reach proper penetration. A FN-FMJ or hardcast round could offer superior penetration.

I either carry 10mm 180 gr JHP Hornady XTP for self defense against 2-legged predators and 10mm 200 gr hardcast Underwood for self defense against 4-legged predators in my Glock 20. I know that the JHP round will go 17 inches. I also know that the hardcast round will penetrate dense animal meat deeply and shatter bones.

It penetrated 7 water jugs if that's any indication. Anyway I normally carry Uw 10mm 200 XTP but I have faith that the 9x25 will do the job in SD. It's no different than a 357mag.
