9x25Dillon

[REDLINE]

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!

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.

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.
