Success! Fired over 50 reloaded 9x25 Dillon rounds with no issues whatsoever. I used a metal straight edge and a piece of .003" shim stock to check the headspace adjustment before locking down the sizing die. Thanks to all for your helpful feedback.

That's great! I'm sure you will have a lot of fun with 9x25.
DM1906 had alot of great points which I do agree with generaly. I would comment that one big reason to have proper headspacing 0n 9x25 and 357sig is that proper headspace will increase the life of your brass. These bottlenecks tend to crack at the neck and shoulders so the less the brass has to blow out to fit your chamber the more times you can use it. Also I have a Berretta in 357sig that won't reliably headspace off the extractor.

veprx4, Like it when a plan comes together! Good to see things are working out for you and this cartridge...

I thought I would ask a question to you guys. I got the 9x25 bug again and want to play with the 158gr deap curl .357 Speer bullet. Looking for some advice on powder and start charge.

[mrpipesmkr]

JT, I can't be much help to you because I have no actual experience loading 158 grain bullets in 9x25. I tend to shoot 125 gr. My Lee manual shows a 357sig load for a 147 gr XTP. I would think if you started at the starting loads for that weight bullet (or slightly less) you would be OK. With Longshot, they show a starting load of 6.5 grains.
If you have 9x25 147gr loads worked up these should give you some idea of a starting load. If not you might try some 147gr before playing with the 158 gr.
Do you intend to size the Speer's down to .355 or .356? I shoot .356 in my 9x25 with no problems but have not shot .357. I think it would work but may contribute to higher pressure.
Another thing to consider is that the .357 diameter may cause jams due to the width of the loaded round at the neck. With .356 I have noticed that I can't use too much crimp as this can create a slight bulge which can prevent the round from fully seating in a tight chamber.
If you don't size the bullets down it might also be a good idea to have some freebore off the forcing cone at least until you have worked up loads and OAL. Of course this may already be dictated by the length of your mag, chamber ect.
Let us know what you come up with.
P.S. Nice to know someone is able to get reloading supplies, tough to find around here right now!

Hello JT, someone mentioned they were loading a 180 grain but I don't remember any load data being discussed.

Gun-adian did some 147 gr with Blue Dot
Hornady 147 gr. JHP-XTP.
CCI #300 primers
5 shot strings

8.5 gr. Blue Dot
Velocity:
1) 1197 fps
2) 1124 fps
3) 1178 fps
4) 1201 fps
5) 1192 fps

9 gr. Blue Dot
Velocity:
1) 1304 fps
2) 1270 fps
3) 1267 fps
4) 1297 fps
5) 1299 fps

While I think it is possible, velocity wise I think the velocity may be a little too low for bullet performance. (fearing the Deep Curl were more for 357 carbine and 35Rem rifle)

Bullet length will be long and seated depths occupying case capacity. I have shot 38Spl using cast and gas checked RCBS 180 gr Silhouette bullets using 8.0 grains of Blue Dot so I don't thing that would be a bad starting point.

Powders like 296/H110 may provide more push with less pressures.

Good luck! I'll be looking to see how you do.

Hornady 90gr. XTP over 14.0 gr. Blue Dot (WLP)

Had one case separate from this small batch (50 rounds)... Brass reloaded for third time. Some of the case shoulders/necks do not look consistent. Used 9mm expanding die as well.

Shoddy work on my part? Ever have this happen?

Thanks, any feedback would be appreciated.

OK first thing is head spacing...It looks like you are setting the shoulder back too much. The case is going inside the chamber too deeply and when held by the extractor hook the case is stretching out when fired. The way to correct that is to back off on the sizing die, you will want the case to fit the barrel and be within 0.0"(Flush to the barrel hood) to -0.002" below as a max.

What is happening is every time you fire them, it is working the brass at the shoulder and usually the separation occurs at the shoulder or neck, however it can separate anywhere on the case as it tries to stretch back out, to fill the chamber dimensions.

I size mine to be as flush with the barrel hood as possible. The less case expansion front to back the better!

Good luck and best regards!

Does anyone have any experience reloading 9x25 Dillon useing Berrys 115 grain thick plated hollow base bullets? Is there any problems using these hollow base bullets?

[_The_Shadow]

Yogi86, welcome to the forum! Here is my thinking on them, the thicker plating should work...I had asked Berry's a while back about their thicker plating for 10mm and they did say that it would be better at higher velocities. With the 9x25, Bullet set back is what you want to avoid, so being careful with neck tension is crucial. Don't over crimp them as to cut thru the plating.
If they were 0.356" diameter that would even be better.

A lot of people don't realize that the Gold Dots are thick plated. Berry's was due to come out with a Plated HP of their own, they were said to be shipping to cartridge manufactures first then as a component product.

Best regards and good luck!
