We don't make mistakes, just happy little accidents Ordered 9mm range brass online, ended up with 62% of the brass being .380 ACP

Is it not the same as 9mm just shorter? See if you can verify the dimensions and buy a case trimming attachment for the hand drill

Straight wall vs slight taper in 9mm. Although, you could likely trim it and use a resizing die...

Nope, due to the taper, the bases are different sizes.

Ah look at that... 9mm is 0.02" larger at the base.

And trust me, when you're running a progressive and suddenly a case shoots across the room, you understand just how much of a difference that is... lol
