I am trying to build the decker .I want to ECM the barrel but it is impossible to find the files to ECM a .380 barrel. has anyone done it? I can only find immortal revolts V3.5 ECM Mega Pack and doesn’t include the .380. I found his ECM guide in the ECM files for the stingray it was V3.62 and it did include the dimensions for the .380, but it only has the STL files for 9mm. where can I get the STL for the mandrel and the other stuff I have been searching for 2 weeks I am going insane!!!
this is what I have found from the guide
.380ACP
8.84mm bore, 9.02mm groves, 9.06mm throat. The .380ACP mandrels has 1:16 twist rate and 6 grooves.
Chamber depth is 14.35mm, Throat depth is 17.85mm and throat is 3.5mm long.
The cartridge headspaces on the case mouth.
METRIC tools use 6mm steel rods and IMPERIAL tools use 1/4 inch rods.
So I’ve never tried ECM and I’m just a rando with a barely passable understanding of barrel sizes
But I think .380 should fire from a 9mm barrel just fine, it’s the chamber that would need to be different.
If that’s wrong, someone please correct me and feel free to call me retarded
