They are turned down to .350 back .670 from the case head and wind up .980 OAL before the crimp. They don't perform as well as my 45 ACP shot loads because they don't use a wad and also have a smaller payload but one of my 380 pistols weighs 1/3 what my "beater" 45 weighs.
And yes handirifle they cycle the action the video in the first post is out of one of my PPK's but here is one with my LCP.
9x23 is long enough but not thick enough to turn, they would need to be formed instead.

Forming is what I did on my 45 ACP shotshells.
I found a suitable donor die in my stash, an RCBS 44mag/SPL die. Ran a file across it and found that it was way too hard to machine.
So I heated it up to take the heat treat out of it.
At that point I drilled and tapped it 1/2-20 and and reamed the inside to resize the case and form the neck down portion.
With the cases formed I then machined down a grade 5 bold to act as a mandrel to push the over shot wad down below the crimp. The crimp mandrel was made with a 1/2" ball end mill and slides over the over shot wad mandrel.
This way you only use the one die, just remove the insert to form and replace it to seat the over shot wad and crimp.
With the old Remington shot rounds I am about out of I had to use a specific magazine but the new formed cases feed with all that I tried, in my "farm" 45 at least.
Cases are made from cut down 308 brass.
Loaded up a few, the wads were cut down to 11/16" and hard to get in on the first one. After that my brain started working and I used the wad guide off of one of my shotshell reloaders.
They hold 84.9+\- grains of #12 or around 425 pellets. Used 6 grains of 231 and over-shot wads punched from a 12ga hull.
Step by step.
They patterned tighter that my other pistol shot loads using Speer capsules, maybe because of the wad.?
15ft
Video link of them running.

You might be able to pull them with an inertial puller and with a foam earplug in the bottom they might not break.
They cost more than a buck ea, only hold 52 gn of shot and you still would have to come up with load data,

Why wouldn't you just shoot the 9mm?
well there is a huge size and wt diff. i carry the lil gun in my front pocket or a cell phone case on my hip all day and nine is,,,, well for special occasions. waliking or mowing you never know when a rattlemoccasin will pop out. i get several a year ....and doctoing horses or losing dogs aint fun.
what is the inside diameter of a 380 case?
i will pull a nine tonight to see what happens.
i gave away my pistol dies so i will be starting from scratch there.
psssst what are you using for the shot in the 380 powderwise.

Can you post a photo of the capsule? Any chance you can weigh it and/or just the shot?
I started out at 2.0 grains of N310 and worked my way up until it cycled 100%.

That's a great idea for you guys in snake country. I have a Ruger LCP Custom and it's the size of and feels just like a wallet in your pocket. Shoots more like a 4" barrel too. I can hit out to 25 yards easily with the thing which came as a huge surprise. That sort of gun would be the ideal snake defense gun for someone who didn't want to lug a hand cannon around. Make the first 2 snake shot. For the 4 legged big troublemakers the noise is the real defense anyways then you have 5 more ready for any 2 legged vermin that might come your way.
I never gave the 380 much thought but now having lugged a cannon around for most of 30 years on the job I prefer to live with minimal and comfortable. Your idea makes a nifty little gun even more handy.
