100g 380 loaded in 9mm brass

[Mattroth54]

I’m converting my 380 reloading operation to 9mm. I have 1000 100g extreme plated 380 bullets. I’ve found load data using those for 9mm. OAL doesn’t seem much different than heavier bullets. Any reason not to use these? I could probably exchange them at cabelas for something else. They’re for general plinking.

As long as they feed reliably you should not have any adverse issue to concern yourself with

Just remember to work up your load.

I laughed until a fart came out.

See you worked up your load and showed signs of over pressure.

There was a thread a while back exactly discussing what you want to do. It was referring to 'mouse fart' loads for target practice/light recoil.

We load exactly what you have (380/100gr) in 9mm re; 'mouse farts' and some stock 9mms will cycle some won't. YMMV.

I’ll work them up and see if they run the gun. Just need to find the gun...

Some pistols aren't going to work well with light bullets regardless of how much powder you use.

Thats it. I didnt realize it was 2017. I must be in a time warp. I thought it was April... Looked back at some threads with the Helix... We were using 4gr of Bulls Eye. YMMV.

Once I find my P365 I’ll work something up and report back to the class.

200 rounds of these ran flawless through the new P365. Nice easy shooting round for this gun. Here’s what I settled on:

100g .355 extreme
4.2g titegroup
1.050 OAL
