9x25 Dillon Load Data

[DRAB_81]

Several members have recently contacted me about my 9x25 Dillon loads, so I figured I would post what I have so far. I'll separate it into posts from each chrono session.

PLEASE USE WITH CAUTION. THESE LOADS ARE SAFE IN MY GUN, THEY MAY NOT BE IN YOURS.

I started @ 11.5gr for a 90gr XTP, since 10.0gr is Hodgdon's listed max for a .357sig 115gr JHP. I have to admit I think it was a little aggressive for a starting point, but I haven't had any pressure signs yet.

I am really happy with Longshot so far. With an average of 1920, and an ES of 18, who could complain? These loads are LOUD! The range I go to is outdoors, and the office is about 50yds away. The girl came out of the office to tell me to stop shooting a Rifle on the Pistol range, but got really confused when all she saw was me and my G20L.

I had previously worked up a few Blue Dot loads, from 13.5gr to 15.0gr (indoors). This was before I had my chrony, and none of these loads showed excessive pressure signs. This time I started @ 14.5gr, and worked up to 15.5gr, shooting through a Shooting Chrony F1 Master. I think I'll try WLP's & CCI350's next, and I may experiment with the OAL. The muzzle flash alone is enough to keep me coming back. Shooting the 14.5gr/CCI300 load indoors produces the biggest fireball that I have personally seen out of a handgun.

These were loaded to tighten up the ES's of my previous testing, while keeping the average velocity over 2000fps. I added a little more crimp this time too.

Brass/Primers all look good, and brass drops within 4ft of my position. I'm going to stick with the 12.2gr load for the 90gr XTP from now on. Now it's time to get to work on the 115gr XTP's.

I also tested some more Blue Dot/90gr XTP loads, this time with CCI350's, and again, a little more crimp. I just wanted try the mag primers out. The sound and flash from these rounds are amazing. The 14.8gr load is my new "wake up the indoor range" round. 14.5gr with CCI300's works for that too.

I also put (10) more of my 90gr XTP/12.2gr Longshot/CCI350 loads through the chrono, just to confirm the numbers from previous testing. They are consistent with my last chrono session, averaging 2048fps with an ES of 27.

Anyone Still Testing 9x25 Dillon with Blue Dot?

I've been testing 9x25 Dillon running 90 gr. Xtp's over Blue Dot(CCI 300),and 6" LoneWolf Barrel. I started @ 15 grs. which may be aggressive, but I've seen many others loading 15 grs with no issues. I do not have a chrony nor do i have a clue how to test/calculate pressure.
So I've been working up slowly looking for signs of over pressure, flattening of primer, case bulge ect ect. I'm now up to 17 grs of Blue Dot which is about like filling the case and stuffing the bullet in, and i have yet to see anything that concerns me with my fired brass. I don't think you could force enough Blue Dot in the case to get over pressure.
Has anyone else loaded this much Blue Dot for this round? I have no idea what the FPS would be on this, but i would imagine from what I've seen that it would be 2000-2100. Any info would be helpful.

Nice first post. Any other pipe bomb recipes you'd like to throw out there?

[TacticalGearJunkie]

Not sure how it's a pipe bomb when i've shot my 17 grain loads alot with no signs of pressure, hmm. I will just assume you have no experience with this round and you are welcoming me to the forum with a negative reply instead of something helpful.

Just because those loads worked in other people's guns, doesn't mean they won't blow yours up. Every gun/barrel is different, even the same model guns/barrels have variances that may affect their ability to handle cetain loads. Environmental Variances (Temp/Elev/BP etc.) will also play a large part in the pressures you will see. It is NEVER a good idea to start that close to the max attempted charge with ANY caliber. I've been loading 9x25 for a while, and the highest Blue Dot charge I have ever seen, myself included, is 15.5gr with a 90gr XTP. I STARTED @ 14.0gr BD, EVEN THOUGH SOME GUY ON THE INTERWEB SAID HE SAFELY LOADED UP TO 15.5gr IN THE SAME MODEL GUN AND BARREL. There is not much Published Data for this caliber, so we have to rely on our friends in the 10mm Reloading Forum on Glocktalk for experimental data. I was the first one to ever use Longshot out of everyone there, so I took what I thought was a conservative shot in the dark. I still haven't encountered any excessive pressure signs, but I see no need to drive a 90gr XTP past 2050fps.

I have no idea how you were able to fit 17.0gr of BD in a 9x25 Dillon case. My cases were almost spilling out at 15.5gr. I do however agree that you may not be able to actually get enough BD in a 9x25 case to cause overpressure. Since nobody has done any pressure testing with this caliber, I use extra caution.

I don't mean to be harsh, but I take loading safety very seriously. I'd hate to see anyone lose a finger or an eye because of load data posted on the internet, much less because of my data. Please be safe, and again, my intention wasn't to rake you over the coals here.

[TacticalGearJunkie]

I understand what your saying. I definitely don't expect anyone to try loading what i did. I'm not sure why your powder is spilling over @ 15.5 grains because i easily get 17 grains in (unless you don't expand the neck with a 9mm expander, I probably gain a grain or 2 by doing that verses not doing it). I admit it was risky for me to load that high, but like i said there were no signs of over pressure and i don't plan on going any higher. I was shooting steel plate rated for .44 Magnum, when i hit it with some hot 10mm loads it barely put a dent in the steel, then i hit it with some of my 9x25 loads and damn near blew a hole through it. I wouldn't surprised if I'm getting 2100+ FPS.

[TacticalGearJunkie]

Also, no offense taken. i understand your concerns. I'm well versed on how dangerous this sort of thing can be. I had an accident with a factory slug i shot out of my Benelli Super Nova that apparently was a double charge, because it blew my gun to pieces as well as taking off half my thumb on my left hand. I have pictures of the gun and my thumb.

It's been a while, but I don't think I was literally spilling over @ 15.5gr. I remember it being pretty damn close though. Longshot outperformed BD in 9x25 Dillon for me, so I haven't used BD since that last chrono session. I load one step at a time on my RockChucker, and I use an RCBS 9mm expander die to bell the cases. If you're up to 17gr, I would also bet you're over 2100fps.

I'm glad you're not just some poor rookie, being wreckless and impatient. I'm always happy to see another guy interested in the 9x25 Dillon. There aren't very many of us around these days.

Also, I'm truly sorry to hear about your accident.

I have noticed many people getting better results and higher FPS with Longshot for .40,10mm and 9x25. I haven't experimented with Longshot yet but i may in the future. I'm mainly using Titegroup for my .40 and 10mm, and Blue Dot for 10mm and 9x25. Titegroup is excellent for target loads because you need very little.

Yeah I'm definitely not a rookie at shooting and reloading, and I'm living proof that no matter how careful you are accidents happen to anyone. I spent hours and hours going over every piece of load data i could find on the 9x25 before i loaded my first round for it. A lot of the data was actually stuff that you yourself posted.
